 21 Jan 2006 6:37 Bus for connecting ARM + DSP |
|
|
|

I am thinking that for some specified application which ARM-base processor and DSP works together.
What's the type of bus between two processors, which could enhance the total computation power?
Are they 'memory shared' (it seems too complicated for s/w design) / SPI/ GPIO (speed too low)?
 I know TI, philips, atmel....they have DSP/Codec + ARM inside single chip. But any sugguestion for discrete them.

Hi
You can use the philips LPC22xx ARM with external bus to connect the dsp as an external memory device
All the best

Hi,
Maybe you don't need additional DSP with ARM core. New ARM cores have support for DSP operations. So choose some ARM9 or higher architecture.

Hi
I think the newst release of AMBA Bus has a fast AHB link to IO's which could be used to connect to DSP

Hi
I think you can use the Ti's newst chips which intergated DSP+ARM.
