FPGA as a Service:Overview of the FaaS f3 SDAccel development environment

Last Updated:Nov 20, 2023

The FPGA as a Service (FaaS) f3 SDAccel development environment is based on Xilinx SDAccel dynamic 5.0. You can develop applications in the FaaS f3 SDAccel development environment based on Open Computing Language (OpenCL). This topic describes the SDAccel development environment for f3 instances.

The following table describes the components of the FaaS f3 SDAccel framework.

Component

Description

Xilinx OpenCL Runtime

The runtime that exposes the OpenCL API to users.

HAL

The Hardware Abstraction Layer (HAL) that adapts the OpenCL runtime to the kernel driver and manages global memory addresses.

XOCL Drv

The xocl kernel driver of Xilinx.

Host Mgnt Drv

The management driver that runs on the host to load the Field Programmable Gate Array (FPGA) kernel.

User PF

The user physical function (PF) interface that is deployed to a VM to provide users with FPGA access channels.

Mgnt PF

The management PF interface that serves as the channel for the host to access FPGAs.

Kernel

The OpenCL kernel module.
