worked with TI DSPs more than a year and it's even hard for me to understand
your arguments. A C5416 DSP has only a 16bit-Core (compared to ARM 32bit) and
this is the reason for the most inefficiencies. All 32-bit variables cannot be
processed in registers (except the accumulators) and all operations on 32bit
variables were translated with calls to stdlib functions. Furthermore the
compiler itself does nothing else than translating the c-code into assembler. The
code is only optimized, if the optimizer is enabled. I had a look on the
efficiency of the assembler output in a number of cases. If the optimizer is on
(g2 or g3) and the Debug Info is disabled, in the most cases I couldn't get a
reasonable better result writing this part of code in assembler. Exceptions are
the calls to stdlib functions. Therefore it is best to start optimization work
in those parts which include a lot of calculations - e.g. IMDCT, Overlap Add
and Spectral Envelope - but I'm convinced this is nothing new for you. </span></font><font

not want to criticise you, especially not because I think you've done really a
great job by implementing Vorbis and Tremor. But I also think that it is not
fair to compare a 16bit-DSP with a 32bit-Microcontroller (which has even more
an assembler instruction set especially developed for efficient c-code
translation). Let us compare the C5416 DSP with 16-bit CPUs of other chip
producers. I have not heard from Ogg Vorbis running on another 16bit CPU. Is
there any port available?</span></font><font size=2 face="Courier New"><span

also had similar problems that CCS does not respond after running a program. But
after digging into the sources I always found the error on my side. Once there
was a stack overflow, once the memory allocated was not available. (Then I
wished that there would have been a check on null-pointers after an alloc.) But
finally the codec works fine, even on a TI DSP (not C5416, but C5510)! Furthermore
I think that CCS has included a number of very nice and helpful features. When
you use DSP/BIOS you can display the current CPU-Load and tools are provided to
measure execution times of functions and modules. Additionally your application
is not limited to one task anymore - multitasking applications are possible. </span></font><font
