We are glad to announce the public release Open Programmable Acceleration Engine (OPAE) 1.4.0 today. The Open Programmable Acceleration Engine is a software framework for managing and accessing programmable accelerators (FPGAs). It currently consists of three main parts, the OPAE SDK, the OPAE Linux driver for Intel(R) Xeon(R) CPU with Integrated FPGAs and Intel(R) PAC with Arria(R) 10 GX FPGA and the Basic Building Block (BBB) library for accelerating AFU development (not part of this release, but pre-release code is available on GitHub: https://github.com/OPAE/intel-fpga-bbb. OPAE is under active development to extend to more hardware platforms, as well as to build up the software stack with additional abstractions to enable more software developers. The OPAE SDK is a collection of libraries and tools to facilitate the development of software applications and accelerators using OPAE. It provides a library for presenting a streamlined and easy-to-use interface for software applications to discover, access, and manage FPGA devices and accelerators using the OPAE software stack. The OPAE SDK also includes the AFU Simulation Environment (ASE) for end-to-end simulation of accelerator RTL together with software applications using the OPAE API. OPAE's goal is to accelerate FPGA adoption. It is a community effort to simplify the development and deployment of FPGA applications, so we explicitly welcome discussions and contributions! The OPAE SDK source, unless otherwise noted, is released under a BSD 3-clause license.
