This document defines the Coherent Accelerator Interface Architecture (CAIA) for the IBM® POWER® 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 software to migrate from one implementation to another with minor changes.
