AR# 47406

Description

This example design allocates 4K of block RAM attached to the M_AXI_GP0 and monitored by the ChipScope tool.

The software then treats the memory as a "shareable device" or "strongly-ordered," and a Vivado Logic Analyzer shot provides the distance between two consecutives BVALID signals on the AXI port for THROUGHPUT.

Solution

Step-by-Step Instructions

1. Import the archived design into Vivado or run zc702_ar47406.tcl to create the IPI project, then export to SDK.
2. In SDK, create a Hello World example.
3. Modify the Hello World example to include the snippet of C code.
4. Program the PL using the BITSTREAM generated by Vivado.
5. Set up ILA to trigger on the BVALID signal.
6. Run the application.
7. Measure the throughput as the time between two consecutive BVALID signals on the AXI Master Interface.
8. The memory access is driven by PS DMA. Burst length is 16.
