FPGA implementation of 2D Convolution using OneAPI and OpenCL

International audienceThanks to High-Level Synthesis (HLS) tools, FPGAs have become an alternative to GPUs for compute-intensive applications. These tools have been developed to provide flexibility in FPGA design at a higher abstraction level than hardware description languages. Major FPGA manufacturers have proposed many HLS tools depending on the target audience. In this paper, we propose a hardware architecture on FPGA for 2D convolution designed through two software-like development tools based on oneAPI and OpenCL languages. This paper also focuses on comparing the oneAPI and OpenCL HLS tools in terms of performance and productivity with the case study of the 2D convolution operator using an Intel Stratix 10 device
