Performance parameters:

 

FPGAThe external bus interface supports 8, 16, 32, 64 bit data bus, which can directly connect with CPU, SDRAM, FIFO, SRAM, external interface chip and other devices.
 
FPGAExternal expansion 32/64M byte 64 bit SDRAM, the maximum working frequency 133M, 8 word burst mode;
 
FPGAExternal expansion of 100 users IO, support 1.8V, 2.5V, 3.3V external IO input and output standards;

 

 

 

 

 

 

Actual data transmission efficiency test:

The development board is tested on the following PC and runs normally through:

The performance test uses the cycle maximization transmission mode. EachDMA block size is 512K bytes, according to the average flow rate of 5 seconds, the number of DMA blocks transmitted within one second is calculated.
