This document defines the Coherent Accelerator Interface Architecture (CAIA) for the IBM® POWER8® systems. The information contained in this document allows various CAIA-compliant accelerator implementations to meet the needs of a wide variety of systems and applications. Compatibility with the CAIA allows applications and system...

A CAPI based accelerator interfaces to the POWER system through a logic unit called the Power Service Layer (PSL).  The Accelerator Function Unit (AFU) contains the logic that implements the unique acceleration function.  This OpenPOWER Accelerator Workgroup Specification defines the logical interface between the PSL...
