From the project
OpenCAPI-Compatible SlimSAS 8x to PCIe Endpoint Adapter
The Open Coherant Accelerator Processor Interface (OpenCAPI) was a standard that had FPGA-based Advanced Accelerated Cable (AAC) Add-In cards such as ADM-PCIE-9H3, ADM-PCIE-9H7, ADM-PCIE-9V3, ADM-PCIE-9V5, BittWare XUP-VV4, BittWare XUP-VVH, and Nvidia Innova-2 Flex.
The OpenCAPI SlimSAS interface is based on PCI-Express. This project is an adapter capable of connecting such FPGA boards to host systmes with PCIe.
