DescriptionOpen Coherent Accelerator Processor Interface
(OpenCAPI) is a new industry standard architecture
agnostic device interface. OpenCAPI enables the
development of host-agnostic devices which can
coherently connect to any host platform which supports
the OpenCAPI standard, providing device 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 while providing high
bandwidth in addition to low latency needed by advanced
accelerators. OpenCAPI encapsulates the serializing
cache access and address translation constructs in high
speed host silicon technology to minimize overhead and
design complexity in attached silicon such as FPGAs and
foundry ASICs. Finally, OpenCAPI architecturally ties
together transaction layer, link layer, and physical
layer attributes to optimally align to high SERDES
ratios and enable high bandwidth, highly parallel
exploitation of attached silicon.
