psl_dma

A block DMA engine works with IBM CAPI interface.

• rtl : A folder with an example to use the DMA engine. The loop_back module get data from DMA engine and loop-back the data to DMA engine.

• app : A folder with APIs and also a testbench to use the block DMA engine.

• sim : Example simulation scripts for Modelsim/VCS/NCSim

• CAPI homepage: https://www-304.ibm.com/webapp/set2/sas/f/capi/home.html, go to Nallatech or Alphadata website (on the right bar Purchase CAPI Development Kit) to learn the information of FPGA cards, and CAPI user guide on Altera/Xilinx edition.

Run Simulation (on x86 linux env)

git clone https://github.com/ibm-capi/pslse to the parallel path of psl_dma.

`----
|-psl_dma
|_pslse

Read the README.md under "sim" directory.

Run with CAPI-card (on Power8 linux env)

git clone https://github.com/ibm-capi/libcxl to the parallel path of psl_dma.

`----
|-psl_dma
|-libcxl

make libcxl first. Then make app.
