Hi guys,

I have a OMAP3530 board with me.
I want to run some applications involving DSP algorithms .
How do i access the DSP processor available in the omap3530 ?
I want to know, How it is done in embedded Angstrom OS running on my
Board.

Thanks and Regards

Bumble.

i get the following kernel messages while booting…
Has it got anything to do with DSP processor’s comfiguration?

Hi guys, i want do add few more details..
I tried to load x-11 Angstrom , which does not work..
So, if I try to use those DSPlinkers, bridges, will they work fine??

Some body, please help..
Thanks and Regards..

hello guys,

i don’t understand why one has to use a different compiler to compile DSP related codes… ??

thanks and regards,

The DSP core is a separate processor with a different architecture and
different opcodes, and will therefore require a different compiler.
Unfortunately I am also a Beagleboard newb and that's as deep as my
insight goes.

The DSP is a completely different kind of thing than the ARM. Think of
it as a second processor that speaks a different language. Another
compiler is required because the DSP can't execute ARM code.

The only thing the DSP and the ARM have in common is that they have to
share the same memory and access t some peripherals.

what happens when i boot the board…?
what happens to the devices that use DSP? Do you mean that, while booting , the kernel uses only the ARM cortex A8 processor of omap3530?
And DSP comes only when required?
Do we need to schedule the Processes?

I need a crystal clear guide… can some body give me any link about it?

Thanks,
Bumble…

Hi,

Is there any need for scheduling the processes while using DSP core of OMAP 3530?

Thanks

Hi guys,

Is there a need to activate DSP processor in order to use it?
Are there no peripherals on Beagleboard that already use DSP processor to function?
Isn’t it already activated??

Sorry guys, i am quite confused with the DSP core …

thanks
