Requirement of SDRAM for SGDMA

[Altera_Forum]

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  Nandish Jasani.
