Hey,

I've got a uni assignment to write about DSP.

How does a DSP processor differ from any other processor? I can't seem to find a great deal of information about this.

The lecturer has pointed us in the direction of a 'Circular buffer' and assembly level commands that are valid only to the DSP processor but am not having too much luck finding info.

Please help!

 

Hello,

On this page of the EDUCYPEDIA ypu will find some links on the DSP subject:

Cheers for the reply, some of those links look pretty helpful.

Although, i'm less interested in DSP processING and more interested in DSP processORs, namely how they differ from any other types of processor etc.

Thanks again for any help!

 

Hello,

The links on this page of the ePanorama are both on DSP soft and hardware:

About two min on google will solve this for you...

But the obvious answers are: pipelined harvard architecture with multiple busses, hardware MAC units capable of doing one or more macs in a single instruction, MOD addressing for circular buffers, minimal use of caches, bit reversed addressing for FFTs, hardware looping to reduce overhead

 

Bertus and guitarguy12387 thankyou! HUGE help!
