request for Memory map of Punyforth #35
Comments
|
This was the picture of the memory map, I can not add it as such on my message.... |
|
I continue exploring punyforth and I have tests and results core.forth alone gives freemem of 16.776 bytes free tcp-repl with all it dependencies and I have been looking at flash.forth dependencies, it has only 1 needs "core.forth" Questions : is this editor working ? It seems it saves to Flash memory, like I previously asked I will try to understand more..... apparently having Rtos and open-boot in the system Kind regards |
No, the text is not copied into the RAM. Punyforth compiles indirect thread code from the text and fills up the dictionary.
This sounds realistic. The freemem word shows the available forth dictionary space, not the free system memory. There is an osfreemem word for getting the free memory from RTOS. Punyforth allocates about 24k dictionary space which means that your program and its dependencies consume about 22k. When I was experimenting with larger dictionary spaces in the past, the system became unstable because not enough memory was left for RTOS. It usually crashed inside the lwip (tcp stack) code when it tried to allocate netcon buffers. So I decided to allocate only 24 forth heap, and leave the rest to RTOS. You can experiment with larger memory settings by changing this line and recompile Punyforth https://github.com/zeroflag/punyforth/blob/master/generic/data.S#L32 If you don't use the wifi and the tcp stack then it'll probably Ok. But an easier way to fix this is to remove unused words from the uber.forth.
There is an experimental editor in flash.forth but you need to use the --block-format parameter of modules.py when generating uber.forth. |

Ok excellent ! In your opinion if I place .space to 50000 will it work ? 30000, 35000 ? which are the limits ? Can we expect in future a memory map of punyforth within the ESP8266 ? I would like to help |
As far as I remember 30k should work but it will become unstable if you use the WiFi a lot.
Punyforth is not a bare metal Forth (at least currently) but it runs as an RTOS task. This task is created by calling xTaskCreate, which allocates some memory dynamically. But I don't know how the memory allocation is handled internally.
That's great. I'm sure this will be useful for others too. |
|
Thanks Attila ! |
|
FYI I made some optimalization in variable: and constant: that reduces their memory consumption. This should buy you some additional memory. |
|
Excelent ! THank you very much ! |
|
Hello Attila, |
|
Hi Gerard, I was thinking about TOS to register optimization earlier (mainly because of speed) but decided not to do it because some of the caveats. There are words like sp@ and sp! which would be difficult to use if TOS was in a register. Also one can write a code that treats the stack as an array which would likely break with TOS optimization. Task switching and exception handling would likely be more complicated as well. Attila |
|
Hello Attila, defprimitive "sp@",3,spat,REGULAR defprimitive "sp!",3,spstore,REGULAR Gérard |
|
Right. I just don't think the extra complexity would worth the effort. But if you think so feel free to send a PR with the changes required. I'm not against it, I know other Forths do this but mainly because of speed (which is not the main concern) and not memory usage. |
|
Hello Attila, |
|
@GerardSontag no I don't know any unfortunately. But there are some projects in github like the esp port of microphython or forthright which can be used as an example. The API of FreeRTOS is well documented (http://www.freertos.org/a00106.html). |
|
It seems that the flash rom is so big enough to add more compiled code into it. So if someone can design the metacompiler to append the code to it that would be great, right? I'll try, and you. |

Hi, everybody, |
|
Hi holinepu, Could you elaborate the problem with create does>? I'm trying to recall how it works. create: always creates a new word with an enterdoes codeword/entrypoint instead of entercol (which is the usual entrypoint for colon definitions). The enterdoes expects a behaviour pointer (which is an execution token of an other word) after the codeword and some arbitrary data after this. It'll push the location of the data part onto the stack and invoke the behaviour word. The default behaviour word is nop, but does> overwrites it with a user supplied word. : create: createheader enterdoes , ['] nop cell + , ; \ default behaviour is nop, does> overwrites thisHere you can see that it creates a dictionary header and inserts the enterdoes codeword as an entry point. After that it inserts the xt of nop. The data part is not initialized. : does> r> lastword link>body ! ;does> replaces the behaviour part with the user supplied word (from the return stack). So a constant for example can be defined: : constant: cerate: , does> @ ;But punyforth uses distinct codewords for variable/constants to save some space. |
|
Dear Attila, variable: can be defined in rom area too, so long as it can provide a number which is a ram address. : variable.base.address hex: 3FFFF800 ; \ 3FFFF800 can be changed according to need. : create:(ram) var(ram) -4 variable.counter +! ; var(ram) v1 see v1 see v2 see v3 \ ****************************************************************************************** see create: \ ****************************************************************************************** |

The decompiler program compiled by punyForth in RAM can be relocated in any address of flash rom now. |

hi, Attila Magyar Thank you for your interest in the source code of punyForth development system. Please bear in mind that the system is still under development so it looks not very clean. We need the help to promote the system so as most users will like it. you can find the code here:https://groups.yahoo.com/neo/groups/armForth/files/esp8266%20punyForth/

hi, Peter Forth and all the others I have some experience in ASYST which use OVERLAY a lot. I still keep one at hand. Frankly speaking I didn't use it very well at that time. Maybe I'll recall that again.> So the technical word, to define your work is you have created an "OVERLAY capability to PunyForth" !
If it has enough RAM space then we don't have to have OVERLAY to switch between different applications. Still if we can get the OVERLAY capability that would be better. It is better to have than nothing, right?
The attached file temp.rar is for wifi and that sort of things. It works fine. I tried to compile ubernew163.forth into it. It was not very stable, so I switch to the other version ( older ? ) temp1.rar and ran dis-compiler in punyforth very successfully.

Thanks, I'll check it out.
When I used to program in LMI for DOS those kind of files that were binaries pre-compiled, were
called -- OVERLAYS --.(other Forths also named this kind of binaries Overlays, and some other compilers
too, I think Turbo C and Turbo Pascal, had that possiblity too, I do not remember well)
So the technical word, to define your work is you have created an "OVERLAY capability to PunyForth" !
We used this to store the EDITOR, the ASSEMBLER the Native code compiler, and any TOOL that
could be used for a task, and then when the task was complete, was not necessary anymore to have
it on RAM, this was very useful because RAM was limited to 64K. (The other secondary use was for distribution
of software tools, without giving a third party access to your full source. )
Thanks again

Hi Peter Forth ! It seems like that you didn't join the win32forth groups before. It's kind of pity that the Win32forth discussion groups lacking such kind of professional guy like you to join. I seldom join the discussion but still I can get the new information from there. I strongly urge you to subscribe win32forth discussion forum so as you can get the newly updated files from ARMForth groups by killing two birds with one stone. For now I just send you the newly updated file combined into one file to you so as you and the others don't have to find a way around. And here you have to go throw the following procedures to expand the memory of the application memory. Tell me if you've succeeded.

Hi Mr Chang !
Thanks for your suggestion. I will try out a bit more in the future to test your add ons for Punyforth.
It seems to be very interesting tough !
I would like to participate from your YAhoo Forum, but I can not enter. Sory for that.
I was thinking is it not possible, you translate this forum to another platform ?

Hi Peter Forth Thank you for giving me the opportinuity to introduce the esp8266 punyForth development system as you already knew.
I like very much Punyforth.,
I started punyForth development system a year ago. I almost completed the decompiler that under punyforth, unfortunately it was not very stable.Only very recently I was invoked by forthers in Taiwan then I started the development of the whole system again.
I triyed to enter YAHOO Group using your link, I could not. It seems I must register first...
It's a big problem for almost members of figtaiwan. I couldn't help. Maybe I can send you by email or so.Or you can join the the conversation on GitHub with the search " request for memory map of punyforth #35 " to know more about it.
Yes, I would like to use Flash external storage to load files to Punyforth.> Did you write any external Flash extension for Punyforth ? One of my problems, with Punyforth, was the lack of program memory.
You can load the source code from external device and compile it into RAM, but with limited RAM you hardly can extend your program easily. It is 24k byte of RAM to render your code. Whereas with the esp8266 punyforth development system we can cooperate punyforth itself with cross-compiler of the development system to attain the maximum flash memory to use as the code space. As for flash external storage I haven't consider it yet.
I said this to Attila. Regrettable I do not have Attilas Email.> I only chatted 1 or 2 times with him over Github, but I do not like this kind of communication. I prefer Email, or Facebook.
He replied me recently on GitHub, but he didn't mention how to expand the code to flash memory. Instead he asked for the source code of the development system.Frankly speaking I prefer every forther can design the development system in a short period of time so as to showoff other language users to say how easy forth is.
I can also send you my program if you like, that talks from Win32forth to Nodemcu> it is not finished, it is an open program , more as "concept" to show what can> be done using Win32forth + VisualFOrth (making the screens and graphics) and ESP8266 Punyforth.
I failed to try VisualForth before, as it is not an urgent event for me. But when it comes that it can combine punyforth with win32forth/VisualForth, I'll be interest in it.Come on, give me one!
It is a good combination for teachers of technology school.I'll say that the development system can be the best teaching material for all grade of school system. Believe it not!? You'll see the development system you've never seen before, see list file for sure!
By the way, you've been using win32forth ( verion 6.15.03 ) intensively. It'll be easy for you to read the program of esp8266 punyforth development system. That way you'll find the main part of it in a glance, I hope so.I insist using win32forth 4.2.67x version for all my design. It's quit stable, whileas other not. Or do you interest in porting the program from 4.2.67x to 6.15.03.

hi, Gentlemen I've been trying to make the code in RAM area to burn into flash ROM area. It is very successful now. The main tricky program to do this is this: : modify(3FFE88C0~heap-400) ( a -- n ) >r* r@* heap-start ( ` 3ffe88a0 ) ` 20 + heap-end ` 400 - between r@* @ heap-end ` 400 - heap-end between not and r@* @ ` 3ffe0000 heap-start between not and
r@* @ ` ffff0000 and heap-end ` ffff0000 and ( ` 3ffe0000 ) = and
if r>* @ 402XXXXX-3FFE88C0 @ + exit
then r>* @ ;
The attached file 40260000.forth is the main dis-compiler program. You can burn 40260000.forth and either one of the two .bin file to the flash ROM, 4026_171.bin / 4026_4026596c.bin. Upon power on, we can execute words or words7 to see the dictionary structure. Try to find the lfa of the last word in flash ROM and executing it by: ` 4026b2f4 heap-start 32 + ! Then we can execute the following words along to see what's going on. words forget interpret? words see see 4026B2F0 org' 402182C8 |||| 4026B2C0 |||| 3230340C |||| 30303036 |||| \ ..!@..&@.4026000 4026B300 org' 6E652E30 |||| 00000064 |||| 40239B2C |||| 402182C8 |||| \ 0.end...,.#@..!@ 4026B310 org' FFFFFFFF |||| FFFFFFFF |||| FFFFFFFF |||| FFFFFFFF |||| \ ................

When I used to program in LMI for DOS those kind of files that were binaries pre-compiled, were
called -- OVERLAYS --.(other Forths also named this kind of binaries Overlays, and some other compilers
too, I think Turbo C and Turbo Pascal, had that possiblity too, I do not remember well)
So the technical word, to define your work is you have created an "OVERLAY capability to PunyForth" !
We used this to store the EDITOR, the ASSEMBLER the Native code compiler, and any TOOL that
could be used for a task, and then when the task was complete, was not necessary anymore to have
it on RAM, this was very useful because RAM was limited to 64K. (The other secondary use was for distribution
of software tools, without giving a third party access to your full source. )
Thanks again

Owing to the fact that the compiled code, i.e. 40260000.bin has been
written into flash rom, There is no need to write the source text file (
ubernew163.forth ) into the flash rom to be compiled after reset or power
on. Instead we can write ( burn ) the simpler source text file (
ram163.forth ) into the flash rom, so as to connect the lfa of the last
word in flash with the lfa of first.program.in.ram.
由於編譯過的程式碼 40260000.bin 已燒入 flash ROM內 所以不需再燒入原始程式 ubernew163.forth
改燒入 ram163.forth 以連接 flash rom 最後一個的 lfa 到 first.program.in.ram 的 lfa

hi, Peter Forth and all the others
I have some experience in ASYST which use OVERLAY a lot. I still
keep one at hand. Frankly speaking I didn't use it very well at that time.
Maybe I'll recall that again.
> So the technical word, to define your work is you have created an
"OVERLAY capability to PunyForth" !
If it has enough RAM space then we don't have to have OVERLAY to switch
between different applications. Still if we can get the OVERLAY capability
that would be better. It is better to have than nothing, right?
The attached file temp.rar is for wifi and that sort of things. It works
fine. I tried to compile ubernew163.forth into it. It was not very stable,
so I switch to the other version ( older ? ) temp1.rar and ran
dis-compiler in punyforth very successfully. I urge you guys to try this
version out first to identify with our endeavor. Ok!?
Best regard Be Forth

I'll say that the development system can be the best teaching material for

system you've never seen before, see list file for sure!
By the way, you've been using win32forth ( verion 6.15.03 ) intensively.
It'll be easy for you to read the program of esp8266 punyforth development

Hi Chang luke ! , ***@***.***
(this email of yours was given to me kindly from Wesley Fig Taiwan)
Nice to meet you and thanks for your kind words on my video !
I like very much Punyforth., I triyed to enter YAHOO Group using your
link, I could not. It seems I must register first...
Yes, I would like to use Flash external storage to load files to Punyforth.
Attila sayd he did one or the other thing, but I could not run his
examples...
(this was over 1 year ago) I do not know how is it now.
Did you write any external Flash extension for Punyforth ? One of my
problems, with Punyforth, was the lack of
program memory. I said this to Attila. Regrettable I do not have
Attilas Email.
I only chatted 1 or 2 times with him over Github, but I do not like this
kind of
communication. I prefer Email, or Facebook.
I am on the Win32forth user group on Facebook also, if you whish send me
your friend request. I like to use Messanger also of FB.
I can also send you my program if you like, that talks from Win32forth to
Nodemcu
it is not finished, it is an open program , more as "concept" to show what
can
be done using Win32forth + VisualFOrth (making the screens and graphics)
and
ESP8266 Punyforth. Alltogether. I think the Sky is the limit.
It is a good combination for teachers of technology school.
Anything you need I am at your disposal.
Sincerely
Peter
( I am also setting up a web page with things I learn here and there, or
things
I would like others know and have a smoother start in Win32forth. Also a
book and PDF collection, and videos as you already know ).

hi, I've completed the function of transfering the code compiled in ram area to the flash Rom area. It is quite easy to use it to extend the program now. I've already send you the pf.rar file, see if you could try it out, please tell me if you succeed. Best regard holi |

hi, everybody The attached file is the complete source file for developing RISC-V RV32I, RV32M aiming to mecrispForth. Hope this does help to the progress of the development. holi

Dear Attila,
Sory if this is explained elsewhere I did not found it
I am very confused without a memory map of Punyforth, I need to understand
what is happening with my reboot problems I am experimenting with
different programs. It is also almost impossible to advance with Forth
without having a memory map of the full system, I feel like shooting
with a machinegun blindfolded ! It is tough.
I am copying below an example of a memory Map of MicroPhyton for ESP8266
please if you can edit it and correct it for Punyforth to help
everybody visualize better how is Flash and Ram used in Punyforth, and
were is our free space going after loading dependencies.
The example of the internal of Micropython on ESP8266
helped me understand a bit further how the Rtos and Wifi will
consume memory etc...
I have many questions left : 1) is Uber.forth at $51000
copyed from flash to RAM before execution ? because it does not make
sense if we have 1 MB Flash , that 96 K or 64 K ram of ESP get so fast
gone ! In my application 1 LCD with i2cbus and 1 wifi Repl , it consumes
all my memory, I have left only 2K ! After that I can almost not add
anything more without falling into constant reboots.
2) how can this 1MB or 4MB of internal flash been better used ? Is it now
a wasted space ?
3) I suppose there is no way to add an external SD card, this would not
help in any sense. What else can be done ?
Mphyton Memory MAP :
----------------------- 0X4030_0000
