What’s New: At Intel FPGA Technology Day, Intel announced the new Intel® Open FPGA Stack (Intel® OFS), a scalable, source-accessible hardware and software infrastructure delivered through git repositories that makes it easier for hardware, software and application developers to create custom acceleration platforms and solutions. In addition, Intel OFS provides standard interfaces and APIs to enable greater code reuse, accelerate development and speed deployment.

“FPGAs have always and continue to enable developers to deliver customized hardware with optimal power, performance and TCO for workloads from the edge to the cloud. With the proven success from our early-access customers, we are excited to launch the Intel Open FPGA Stack, with its demonstrated ability to dramatically both reduce the development time and also increase code and hardware design reuse for customers and partners looking to accelerate their workloads.”
–Dave Moore, Intel corporate vice president and general manager of the Programmable Solutions Group

Why It Matters: The challenge for any new FPGA-based acceleration platform development – comprised of FPGA hardware design, Intel® Xeon® Scalable processor-ready software stack and application workloads – centers on how much to develop from scratch versus reuse or license.

Intel OFS provides a customizable software and hardware infrastructure that satisfies many of the pain points for hardware, software and application developers, including modular and composable code from which to develop the FPGA design (“take and tailor”), open-sourced and upstreamed code to the Linux kernel enabling open-source distribution vendors to provide native support to third parties and proprietary Intel-OFS platforms. In short, the respective values to hardware, application and software developers are customization, easy portability across Intel FPGA platforms and native support in major OS vendor distributions.

Now, board developers, original design manufacturers and customers can leverage a common infrastructure with standard interfaces to jump-start their FPGA-hardware development. Application developers can achieve a better return on their developments with greater portability across different Intel OFS-based platforms. Leading open-source software vendors can respond to customers’ needs to offer expanded support for FPGAs as they do for CPUs and GPUs under existing and new contracts can now use Intel’s open-sourced and upstreamed code.

What’s Next: Developers interested in trying the new Intel OFS for their next project or would like details on the Early Access Program (EAP) should contact an Intel sales representative to get started. The EAP for Intel OFS runs through most of 2021.
