Is it possible to know the interconnect bandwidth.

One of my colleagues asked me if he can use one of these joined ARM and DSP processors to replace his current FPGA+DSP setup. His main concern is can he shift data between each element and RAM as quickly as before.

He could not find a figure for the bandwidth of the L3 interconnect.

The traffic involved would be duplex up to around 30 Gbit/s, as a total of smaller flows between MAC, RAM, DSP and ARM.

It would seem within the capability of a bus which supports DD3, but he would like a document refrence?

Thanks in advance,

Chris

 

  • Chris,

    L3 is a high bandwidth interconnect that operates at frequencies of 500MHz, 250MHz and 125MHz.  The Crossbar is a low latency, high BW connection mostly between processors and memories or shared links.  Please refer to the Bus Interconnect section of the device TRM for details.
