I thought I would mention here that I have created and published a

Hello,
I was thinking about how to make a bigger projects where I can possibly need
more than 64kB of memory on Z80 (or other 8-bit architectures as well).
There is a memory mapper in the design and one can map 8kB segments to the
range of Z80 CPU.
Has anybody seen some method how to do it

Just one remark to this. Several years ago I ported SDCC (SVN version 5568)
to ST7 and testing looked OK.
I had a look and ST7 and 6502 are very similar architectures. Same A,X,Y
registers. SP is 16bit for ST7, status bits are different, probably
instruction set and boot vectors as well.
Hi Jonathan,
how are your plans to support 6502 in SDCC going ?
Last week I got to TurboGrafx-16 game console and currently thinking how to
program it in C. My idea is to create HuCard with SD CARD and RAM. Simple
bootloader chooses the game from SD card, loads it into RAM and runs it.
Hi Philipp,
thank you for updated tables. But it seems that you forgot to update texts ?
I can see that SDCC's Dhrystone and Coremark values are the highest but text

for speed outperforms all others". That does not corresp
Hello,
I found following page https://stm8-binutils-gdb.sourceforge.io/ stating
that patch for SDCC 3.6.0 is necessary.
"SDCC already had a back end for stm8. Unfortunately not so much debugging
info although most of the debugging code was already available. However it
is still lacking dwarf CFI
"
Those scores are normal for current SDCC. SDCC STM8 integer performance
has improved a lot since the 3.6.0 release. SDCC now achieves higher
Dhrystone scores than any other compiler for the STM8.

Hello,
I am programming small application for driving GSM phone.
I have "const unsigned char" strings (which are compiled as retlw instructions)
and SendToGSM( const unsigned char *pString) function which sends the strings.
But I noticed there is a big overhead when calling the SendToGSM() and

Hello,
I'd like to move some strings like CONNECT, PASSWORD, USERID etc. from code to
eeprom to spare memory. How can I statically initialize EEPROM ? I tried
something like:
unsigned char at 0x2100 EEPROM_CONNECT[] = "CONNECT";
but SDCC does not recognize that this should be directly stored i

Hello,
I tried to compile AN724 ping.c code for simple PPP connection but got into
troubles with code size. In PDF there is a note about 2170 words of code.
After I ( ...ported it and... ) compiled it I got last code cell 0xd27 - it is
3367words even with "static" functions. It can't fit into s
94 matches
