Acceleration Acronym List
Use the following table as a reference when reviewing the release notes.
| Acronyms |
Expansion | Description |
|---|---|---|
| AFU |
Accelerator Functional Unit | Hardware Accelerator implemented in FPGA logic which offloads a computational operation for an application from the CPU to improve performance. |
| AF |
Accelerator Function | Compiled Hardware Accelerator image implemented in FPGA logic that accelerates an application. An AFU and associated AFs may also be referred to as GBS (Green-Bits, Green BitStream) in the Acceleration Stack installation directory tree and in source code comments. |
| ASE |
AFU Simulation Environment | Co-simulation environment that allows you to use the same host application and AF in a simulation environment. ASE is part of the Intel Acceleration Stack for FPGAs. |
| FIM |
FPGA Interface Manager | The FPGA component containing the FPGA Interface Unit (FIU) and external interfaces for memory, networking, etc. The FIM may also be referred to as BBS (Blue-Bits, Blue BitStream) in the Acceleration Stack installation directory tree and in source code comments. The Accelerator Function (AF) interfaces with the FIM at run time. |
| HSSI | High-speed Serial Interface | Reference to the multi-gigabit serial transceiver I/O in the FIM and the corresponding interface to the Accelerator Functional Unit (AFU). |
| OPAE |
Open Programmable Acceleration Engine | The OPAE is a software framework for managing and accessing AFs. |
| PIM | Platform Interface Manager | An abstraction layer for managing top-level device ports and system-provided clock crossing. |
| PR |
Partial Reconfiguration | The ability to dynamically reconfigure a portion of an FPGA while the remaining FPGA design continues to function. |
