LocalLink SDMA maximum Packet Size

Jump to solution

Hi,

I have found nothing in the adtasheet of the mpmc about that.

Is there a maximum packet size for any scatter gather SDMA operation in the mpmc of Virtex-5 HDMA?

I need to stream larger chunks of data (512 Byte up to 256KByte) into/from memory to an external hard disk and I need scatter gather.

 

I was thinking of using the SDMA/HDMA LocalLink. Performace should be up to 50MByte/s. Is this realistic to achieve in Virtex-4 or Virtex-5 with the powerpc?

It works. Packet sizing works really good. I'm sending and receiving packets of 512K and more over my custom IPcore.
