Hi We have been disappointed with the performance of the VisualDSP++ C++ compiler, for code written in C or C++. Manual coding in assembler often yields much faster code. In contrast, the TI DSP C compiler seems to yield excellent, optimised code. Do other people share this opinion? Can anyone at ADI comment on whether this issue is being addressed? David

I've recently dug out an old 21061 Eval board and started 'dusting off' some brain cells by running the demos with EZSharc and VisualDSP. I'm trying the fft.c routines, and it appears to work (sort of!) in the EZSharc GUI, but when using VisualDSP to modify/build/display the results, I don't see what I expect for output. When I execute the code and plot the data, I see the expected waveforms for...
