The OpenCAPI standard, previously supported by technology companies such as AMD, Xilinx and IBM, wasAnnounceIt will be merged with the currently adopted CXL (Compute Express Link) standard, and all OpenCAPI standards and assets will be incorporated into it in the future.CXL (Compute Express Link) Standard SpecificationInside.
The OpenCAPI standard originated from IBM's existing CAPI protocol for communicating between accelerator components and CPUs. However, due to low overall usage and AMD's shift to its own Infinity Fabric protocol, which allows CPUs to communicate directly with GPUs used as accelerators, and Xilinx's integration into the AMD ecosystem, the OpenCAPI Consortium announced that it would incorporate its standard-setting assets into the CXL protocol.
Currently, the CXL protocol has been supported by many chip manufacturers, including Intel, NVIDIA, AMD, Micron, Samsung, Arm, IBM, Google, Huawei, Cisco, etc., and is applied to the design of their chips, memory, accelerators and other products. This allows for faster communication efficiency between CPUs, accelerator components and memory modules, thereby corresponding to faster and more powerful computing efficiency performance.
After the OpenCAPI-related standard resources are incorporated into the CXL protocol, it means that the OpenCAPI alliance will no longer continue to exist and develop in the future, and the related technologies will continue to be applied in more chip designs through the CXL standard specifications.
