What do you get with these packages ? If I understand correctly you buy the
card
and a music production software. You don't have the software development
environment for *the card*. Is that correct ? I.e., in my understanding you get
"the PC, the operating system and software applications", not VisualC++ or
BorlandC or CodeWarrior or whatever.
Now suppose you have a 2-Pentium motherboard. How do you compile code
for it ? Normal compilers generate code for a single processor. It depends on
the operating environment and how much you know it, and... I don't want to
loose myself in a huge something...
Now here we are: always in my understanding, when you have a single TriMedia
you buy the SDK for the TriMedia (Philips or CodeWarrior) and that's all.
You only need to know a little your card, addresses etc.
When you have 4 Sharcs, you buy a compiler for the Sharc and you have nothing.
You need a full understanding of the communication protocol on the card or
a compiler for that card. Am I wrong ? And then come the multi-dsp development
environments. And the kilodollars. The complete SDE+IREF for the TriMedia
is instead 2400 CHF for a University, i.e. 1600US$ (card+compilers + simulator+
profiler+libraries + MPEG-2 and AC-3 decoders, etc...). You have the same
for the
SHARC, but for ONE sharc. IMHO.
I hope that somebody can help me to see things better, if I need so.
Best regards,
Giorgio
