LPC900/80C51 Compiler Toolchain

Hello,

I am starting a small project on LPC932. There seems to be quite a few
toolchain options out there:
Keil
Rigel
Raisonance
IAR
SDCC (open-source)

Which one would you recommend?
In my case, it is a very small project (I might even fit into the 4K
limited commercial kits), but if SDCC is a decent compiler, it will be
useful if I have future projects on this platform.

Thanks
Eugene

We are using the Raisonace tools, and are fairly satisfied with it. It
has a good price/performance ratio, compared to other brands.

You might also have a look at <http://www.wickenhaeuser.de/> for their
uC/51 package. It also is rather cheap, and the demo is limited to 8k
(which is enough for most LPC900 devices due to their flash sizes). I
didn't look at that software deeper yet, however.

I would suggest in this order

Keil
IAR
Raisonance
Rigel
SDCC

Keil and IAR are very much more advanced than the rest.  Keil 
particularly can do aggressive data overlaying which is often more 
crucial  than the limit on memory addressing the eval version.

Infact I have known the Keil eval compiler to get programs to fit ant 
run where the full versions of other programs can not.

SDCC is not what I would call "decent"  It may be unlimited but as I 
said the lack of optimisation means you will run out of Data space and 
possibly code space.

Also there is a lot more to the 8051 variants than just changing the 
header files. TO start with the LPC932 has INTERNAL  eXternal DATA 
memory..... The Keil compiler will handle this correctly.

Start with the Keil compiler.
I would put the SDCC as a last resort.

Anyone got any figures comparing any of these with gcc? Maybe for a
bit of open source software? (e.g. Lewin's DOSFS - or a another similar
sized project). How big is it when compiled with gcc, and with any of the
above compilers. I'm more interested in code size rather than run-time
performance.

Regards,

Paul Taylor.

Doesn't have to be 8051 target.

For code size (I assume you mean both Code and Data data usually being 
the critical one )  the only options are Keil and IAR in that order. 
GCC is not in the running.

Then it depends on the target.  GCC is  closer to commercial performance 
int he 32 bit areas than the 8 or 16 bit.

oops - I haven't used/looked at the 8051 for years, and just assumed that
gcc was ported to 8051.

As far as I know it is but It would not be a practical answer.

Thanks Chris, that was a very informative answer. I will give Keil a
try, and see if my program fits into 4K. All it does is managing I2C,
SPI and some GPIO control lines. I think it should be able to do it.

Eugene.
