OpenCAPI3.0_Device_RefDesign

OpenCAPI3.0 Wiki

Goal

This repositery contains all necessary hardware description to use the OpenCAPI(OC) technology available in any Power9 processors. It contains the TLx and DLx blocs, require to connect to the TL/DL of Power9

It can be used to prepare the code of an FPGA:

• either in standalone mode, to basically attach a card containing an FPGA to the Power9 OC link
• or as a submodule of OpenCAPI Acceleration Framework (OC-Accel).

In the latter, OC-Accel offers a way to program the FPGA without pain, using HDL langages or HLS (high level Synthesis).

OC-Accel doc can be found here:
