Not exactly.

The truth is that the TI's C6000 assembly - like most RISC assemblers - is
very simple and straight forward.The arhictecture is VLIW and hence
load/store based;Hardly 60 instructions and that too highly orthognal and
regular.

having said that, with TI's C6000 DSP's you would hardly every be needed
to write stuff in assembly(if ever, less than 10% of your code)

It is my experience that the tools will achieve upto 80% efficiency of
hand coded assembly; An expert tool user might be able to take this figure
close to 90%. (Mind you, all this without having to program anything in
assembly)

What I indeed said was that if you wanted to achieve that extra 10% or if
you wanted to *know* for your own sake how the tools do software
pipelining technique, then it requires quite a bit of time and skill. It
can sometimes take about 6 months to achieve this level of skill. But only
very projects and only few engineers would need to gear up to this level,
simply because the tools are fantastic.

I will promise that if you can do that the results would be fantastic bot
from the point of view of your own career (VLIW *IS* the future) and the
project.
