Vasanth Nayak (INDIA)
I wanted to know whether there is any significant difference in performance between VDSP C/C++ compiler and the uClinux blackfin GCC compiler ?
It would be good if there is any link documenting any performance difference.

Hi Vasanth, good question.... Below is some info I found in the Forum itself , I thought will share it with you :
" if you just want to compare toolchains, they are pretty close - VDSP beats gcc in some benchmarks (fixed point signal processing), gcc beats VDSP in others (floating point, control code).
gcc also believes that ANSI C is a specification(rules to be followed).
VDSP believes that ANSI C is a guideline (suggestions, but performance optimizations are normally more important).
It depends on what you want.
If you are looking at running Linux on the Blackfin - there is no choice - it is only supported by gcc. "
