 Accelerator Function Unit Interface

 Chapter 11, AFU Descriptor Overview describes the interface facilities that are provided by the POWER Service Layer (PSL) for the accelerator function units (AFUs). The facilities in these sections of the document provide the AFUs with the ability to read and write main storage, maintain coherency with the system caches, and perform synchronization primitives. Collectively, these facilities are called the accelerator unit interface (AUI).
