Acronyms Expansion Description
AF Accelerator Function

Compiled Hardware Accelerator image implemented in FPGA logic that accelerates an application.

AFU Accelerator Functional Unit

Hardware Accelerator implemented in FPGA logic which offloads a computational operation for an application from the CPU to improve performance.

API Application Programming Interface A set of subroutine definitions, protocols, and tools for building software applications.
CCI-P Core Cache Interface

CCI-P is the standard interface AFUs use to communicate with the host.

DFH Device Feature Header Creates a linked list of feature headers to provide an extensible way of adding features.
FIM FPGA Interface Manager

The FPGA hardware containing the FPGA Interface Unit (FIU) and external interfaces for memory, networking, etc.

The Accelerator Function (AF) interfaces with the FIM at run time.

FIU FPGA Interface Unit

FIU is a platform interface layer that acts as a bridge between platform interfaces like PCIe* , UPI and AFU-side interfaces such as CCI-P.

MPF Memory Properties Factory The MPF is a Basic Building Block (BBB) that AFUs can use to provide CCI-P traffic shaping operations for transactions with the FIU.  
BBBs Intel® Basic Building Block Intel® FPGA Basic Building Blocks are defined as components that can be interfaced with the CCI-P bridge.

For more information, refer to the Basic Building Blocks (BBB) for OPAE-managed Intel FPGAs web page.
