Requirement of SDRAM for SGDMA

Hi, 

 

We are using SGDMA for TSE MAC in our Cylcone-IV Custom board. 

 

As per Altera doc. for SGDMA Core, we understand SGDMA requires 2 memory interfaces.  

 

 

  • One is Descriptor memory - We have used onchip memory for this. 

  • second is data memory which is indicated as sdram in altera doc. can we use onchip memory in place of sdram? 

 

 

Thanks in Advance
