Ethernet send the data in SP601

sp601 ethernet ddr sram

 

Dear all

 

I build the a project using SP601 Kit Board

 

I must use import the singal data to microblaze to calculate for my project

 

but the signal have 4096*8192 float data, and in SP601, the fpga has not enough the BRAM to load the signal data

 

 

 

I have a idea, because the kit board has 128M external memory space,

 

I want to use the the Ethernet send the 4096*8192 float data to DDR RAM using MicroBlaze,and read the data from DDR

 

How To ?:smileyhappy:

You'll need mpmc as an interface to DDR and either ethernet_lite or temac for Ethernet. Providing you have an application that can send data from PC using ethernet, the rest should be fairly easy. Receive data from temac/ethernet_lite and write it to DDR. You might want to use DMA to off-load the processor.
