Zynq Ultrascale+ MPSoC ZCU102 vs Zynq-7000

Hi

I have a question about performance of ZCU102 vs Z7020 boards for the same application.

I read the related guides for both of these boards, It said z7020 has 4.9 Mb RAM and ZCU102 has 32.1 Mb Block RAM.

I want to know how can I calculate the latency of them for the same application that needs at least 150 MHz clock frequency.

 

thanks

Hi @SaDaR 

If i understood correctly you are looking for CLK-to-OUT latency for Block RAM in  Zynq ultrascale+ and Zynq 7000 based ZCU102 and Zynq7000 boards.

Block RAM switching characteristics in respective datasheet of devices gives this specification 

https://www.xilinx.com/support/documentation/data_sheets/ds925-zynq-ultrascale-plus.pdf 

https://www.xilinx.com/support/documentation/data_sheets/ds187-XC7Z010-XC7Z020-Data-Sheet.pdf

Here is the table for BRAM switching characteristics  for ZCU102 , you can find same in Ds187  (Table 65) for Zynq7000zcu102.JPG

 

Configuration latency is based on registers stages in the output.
