The MIPS (meaningless/marketing indicator of processor something)
number needed depends on many things, including the encoding algorithm,
the compiler and optimization level, how much time or beer the compiler
and/or marketing team spent cracking dhrystones or other benchmarks,
bandwidth and latency of the memory system used by the DSP, etc. etc.

Best result might be to run your codec on the DSP and measure its
performance on some selected example data streams.


IMHO. YMMV.

Hi all,

can anyone give me a pointer for the following:

How to assess MIPS requirement for video encoder on a particular
DSP processor. This is to see the feasibility of implementation.
Let's say processor freq. is f, frame rate of encoder is 25 fps.
size is 720x576.

Thanks n regards,
