ST7 C Compiler choice : Cosmic or MetroWerks?
2003-10-23 12:39 PM
When developping an application in C for ST7 micros, you have to choose between 2 C compiler : Cosmic or MetroWerks.
Now I am at this step, I have to make this choice. Can you please give me your feedback on this? 1- Have you noticed some differences between the 2 C compilers? (optimization, size of the code, timings, prices, options) 2- What features are included in one compiler and is not included in the other? 3- What are the advantages and drawbacks for each compiler? Thank you very much for your help. Best Regards2003-10-23 09:48 PM
I would recommend cosmic out of the two.
Cosmic gives slightly better optimisation as well as the choice of either using a software or hardware stack - metrowerks only has a software stack. I also think cosmic is slightly cheaper, it was anyway. Don't bother with zap (save the money), just use Visual Debug. Regards sjo2003-10-25 11:13 AM
thanks sjo for your answer!
any other comments from other users?2003-10-30 01:02 PM
Is there anyboday else who had experienced using the 2 compilers? and that have noticed differences between them? (in term of generated code size and speed, speacila optimizations).
Thank you2003-10-30 07:56 PM
Hello
I am FAE of STMicroelectronics and i am getting this question all the time . What i am learning from my customers that all the programmer like the Cosmic but the Metrowerks give more optimaize code . Latino2003-10-30 08:02 PM
I have tried both and finally choosed the cosmic !
I like the Cosmic thing, highly optimized towards code efficiency even their maths libs are impressive but their editor (idea) is pure BS.2003-11-02 11:01 AM
Thank you both for your answers, anybody else have got comments on this subject?

Yes thats true thats a difficult choice to make, it could be a good idea to discuss all the differences between these 2 compilers.

Compared to cosmic, Metrowerks is the right choice to take care of the codesize and it has some good compiler options to reduce both ROM,RAM.
( It all depends on the way in which the program has been written ) KrSel
