|Ron Kreymborg's SmallC for AVR
||Nice SmallC implementation with source code.
||No longer free, will cost $49
|SPJ Systems' C-AVR
||Almost-ANSI C, generates assemble code that can be assembled by AVRASM
||All devices with SRAM
||Basic compiler for the AVR. Optimized for small code.
||Basic compiler for the AVR. Hardware emulator for LCD display etc.
Simulator under development. Highly compatible with Microsofts QB/VB
|GNU C for
||AVR port of standard EGCS with source code.
||AVR port of the LCC compiler, with source code.
|AVR-GCC for DOS
||DOS and Windows ports of the GCC compiler, with source code
|IAR's C compiler
||Windows and DOS
||Commercial ANSI C compiler. Demo available. Probably the AVR compiler
which generates the best code.
||Commercial K&R (with extentions) C compiler for the 1200. Integrated
Development Enviroment looks like Borland C IDE.
|Dunfields AVR development
||MicroC, includes IDE, optimizer, assembler
||DOS, Windows, Linux
||Full ANSI C compiler. Imagecraft claim only 5-20% bigger code than
the most expensive compilers.
||$199, professional version $499
||All parts with SRAM
||Pascal compiler with IDE and floating-point support. Integrated
with AVR Studio. Supports multi-tasking.

||Pascal compiler with IDE
||All parts with SRAM
||Pascal compiler under development.

* Price varies from country to country. IAR also has a Baseline version,
which costs about 1/3 of the full package. It does not support the Mega
parts, it does not have support for floating-point numbers, and it does
not include technical support.
Don Kreymborg has decided to charge money for his compiler. This makes the various GCC etc,
C-compilers seem more attractive. Among the commercial compilers, I think the compiler to
for is Imagecraft. There are now a lot of commercial C-compilers available for around $200,
but I haven't had time to look into what differentiates them yet.
Also, for us Pascal junkies, Embedded Pascal seems nice. I haven't had the time to test it
yet, but I've heard some good things about it.
PascalE also seems nice, but is too expensive for my tastes.
Finally for those projects where money is no object, the IAR C compiler
is the best compiler (in terms of efficient code generation) available
for the AVR. This is no shock, as IAR provided input during the design
of the AVR architecture... Also, IAR has compilers for a lot of other
microcontrollers, and they all share the same interface.
Update 16.01.2000 : I've now finished with my master's thesis, and I've
also (almost) finished moving to my new home. Hopefully, I will have time
during the next few weeks to write some code. The plan is to write code
for a MIDI-CV converter for the two compilers I've received test copies of
(IAR and SPJ Systems), and use my experiences with the compilers to write
a first impressions test. After that, I will gather benchmark code to test
the code generation properties of the compilers.
Update 31.07.2002 : First update in two and a half years... Sorry folks,
but I haven't had time to do anything with this page in a long time. I do
more than enough work with MCUs at work, and I do not have energy to use
my free time on microcontrollers as well. However, it seems that some
people still visit this page, and I will correct outdated info when I am
informed of changes. So, if something is incorrect, please let me know and
I'll fix it.
Matt Tidwell has a page where some
benchmarks for various compilers are presented.
The information on this page is believed to be accurate. I have received review copies of some of
the compilers, but most of the info on this page is gleaned from web sites. Hopefully this will
change as people send me review copies of their compilers, and that I get some free time to test
them. The comments in this page are based on my own opinions,
so your milage may vary. If anybody finds any factual errors in this page, please contact
the author. Any commercial vendors wishing to submit products for review,
are free to do so.
