Abstract

Open Coherent Accelerator Processor Interface (OpenCAPI) is a new and open industry standard device interface. OpenCAPI enables the development of host-agnostic devices which can coherently connect to any host platform which supports the OpenCAPI standard including accelerators and emerging memory technologies. This high performance bus provides attached devices with the capability to coherently cache host memory to facilitate accelerator execution, perform DMA and atomics to host memory, send messages and interrupts to the host, and act as a host memory home agent. OpenCAPI utilizes high-frequency differential signaling technology that provides high bandwidth in addition to low latency needed by the emerging advanced memory and storage technologies.
