hi

hi

can anyone help me how can i port my image processing application which
runs currently at 2ghz p4 on a
1) dsp which does not require computer
2) arm board processor

how much will a dsp cost for a computation power equal to 4ghz intel P4

i would be highly obliged if somone could help me
thanks in advance

To ask a new question, start a new thread.

To answer answer your question, one would need to know many details of 
your application. The instruction mix and the effect of cache all have 
an influence on the outcome.

hi jerry

i am highly thankful, i hope you can help me.
i don know how to start a new thread, i started a new topic.
i have made a opencv c++ machine learning application which runs on 2
ghz pentium processor in real time uses 20 mb ram
and 100% cpu consumption.

basic instructions are accumulation ,addition and subtraction.

basically i just wanted to know much costly the dsp would be to port my
program.
i want to this dsp to be installed in a car which would captures images
from a camera and preocess it .

i was looking at tigershark dsp processors from analog devices.
i am confused that these processors come on a board which does not
require any interfacing to a computer
or this processor has to be put on some other dsp board which is then
plugged into a pci slot of computer.

i wanted to make my system independent of computer and put it in a car.

waiting eagerly for your valuable reply

thanks in advance

For the typical DSP tasks, the computing power of a single core DSP is 
about 3 times higher compared to that of single core Pentium at the same 
clock rate.

It depends.  Several hundreds of US dollars.

OK, I take your obligation.

It's not the operations so much as the sequences.

The chip would be cheap enough. Have you ever built a working computer
from parts? A lot of equipment is needed to get it running. Even laying
out a circuit boars is an art that would need several tries from a
beginner. Buying a working board you can program is a better option, so
it's not the cost of the processor, but the cost of the whole setup.

A new thread is started by pressing "write" (in mozilla-like browsers)
rather than "reply".

If you have your application running on a laptop, you will find that a
small inverter to run it is cheaper than any replacement computer you
could build or buy, and comes from the package ready to be used.

That may or may not be a problem, depending on what the fundamental
algorithms is.  If it suits a DSP, then you might be in luck.  If you
have lots of branching maybe not.

Or it may suit an FPGA implementation better, at least for part of the
algorithm.  This is one method of cost-optimisation I have used in the
past.  

When you say real-time - how many frames per second are you
processing?  And do you have to meet that target *every time* (hard
real-time) or is it OK to miss the deadline sometimes?  Can you tell
us what the application is?

OK, that helps - what are the memory access patterns like?

Are you using floating point or fixed point data types?

What kind of camera? The interface will make a difference, some DSPs
can be directly interfaced.

We at TRW Conekt have lots of experience in putting image processing
systems in cars, we've been doing it since the early 90s
(eg. http://www.conekt.net/docs/LDW%20V1.0.pdf - sorry there's no
boggo html page).  Contact me directly if you'd like us to help.
