I'm strugling making the right choice for our new board.
I Need something like 2 GFLOPS in order to process audio.
Audio is sampled with 44Ks/s externally and internally at 10xFS.
I have been aiming at the ADSP-21161 or ADSP-21261 as a target.
I know there are 2 ways of processing; Parallel and serial.
I have no clue how to create a parallel system ( bus arbiter, software ).
Does VDSP divides the code over the DSP's or do you have to program th
parallel processes manually?
I do know how to create a serial system, but it's not that flexible.
Anyhow the board is less compl...Parallel program to on-line program
I'd like to write a program that runs at the same time as an on-line
program. It should be able to read the messages that are sent to the on-line
program. By on-line program I mean one that receives input from a web
connection. I suppose I'd have to discover what port was being used, by
trial and error, but I have no idea how to go about the job. Any ideas?

We want to run a program in a system of parallel processors. The
program is consisted of a large number of "N" processes which will run
in a small number of "n" processors. Since the communications between
processes are quite time consuming, we assign processes that
communicate with each other to the same processor. To minimize the
time for completing the processes we could assign them all in one
processor but this eliminates the advantage of parallel processing.
This means that there is a requirement for handling the process load
in each processor. The requirement is that each processor should
contribute equally in the processing.
The problem could be modeled in the following way: We have a set Ci,j
of communications between processes i and j. Assume that its process
requires the same processing power. This means that its processor is
assigned with the same number of processes. Use an Evolutionary
Algorithm to assign "N" processes to "n" processors.
Could someone help me with the source code needed for this problem?
Preferably in Matlab or Java... but any other language is acceptable.

The description of some processes can be mis interpretted. The classic
example is this:
"The requirements of a software program drive the design of its code
elements. These must be implemented and tested carefully."
That's too simple to be false, but thousands of shops misread statements
like those. They hear, "Collect all the requirements for a program before
designing its code. Finish the design before implementing any code. After
writing the code, carefully test it to remove bugs."
Worse, some sources actually teach you to work in long phases like that.
They cause major trouble.
If several months (or longer) elapse between collecting a requirement and
testing it, you might not know if you got the requirement right. Testing
reveals this. If months elapse between designing the code and writing tests
for it, the code might not have been written in a way that makes testing
All those situations prevent good feedback. The best processes require teams
to collect immediate feedback on each of their decisions. If they decide to
write feature X, they should commit to design, implement, test, and deploy
that feature within a week. This discipline forces as much feedback possible
on each decision.
The best process...Japanese eBooks, programs, games, programs, other ...

I am a newbie and going through "The C programming language" by
Kernighan & Richie on my own time (I'm not a programmer but I want to
learn because it can save me time in my normal job, and it is kind of
fun). As I go through the book, I seek to do all the exercises because
they are very useful, and good, but it seems like I am just stumbling
through somewhat. In particular, I don't really know how to think about
"catching errors", or how my thought process should be. Right now, I
just try to come up with an algorithm by following the book and
improvising. I'll then try to test my code by throwing different things
at it (for instance, different types of input in different forms) and
see if it breaks, I then try to figure out why it broke and then patch
in the fix. My time is somewhat limited and I cannot at this time take
a C class at a junior college, but I was wondering if this is just part
of learning? Do I just need to continue reading various texts,
practicing, and studying code and I will acquire error checking and
more robust code over time? Any suggestions, hints, words of advice,
would be greatly appreciated. Thanks very much.

My dear programmers and hardware engineers , as you have seen
me here on this forums, i have showed you how to reason about
parallel programming and synchronization mechanisms,
parallel programming is not hard i think, since i have
worked on it for sometime now, because to know what is a race condition
is something easy, and to know what is sequential consistency
is simple and how to make a correct sequentialy consistent program on
weak and strong memory models and such is also not so difficult... and
to know what is lock convoy or priority inversion is
something easy ...How good are you at programming?
