Abstract

Modern algorithms for virtual reality, machine learning or big data find its way into more and more application fields and result in stricter power per watt requirements. This challenges traditional homogeneous computing concepts and drives the development of new, heterogeneous architectures. One idea to attain a balance of high data throughput and flexibility are GPU-like soft-core processors combined with general purpose CPUs as hosts. However, the approaches proposed in recent years are still not sufficient regarding their integration in a shared hardware environment and unified software stack. The approach of the HSA Foundation provides a complete communication definition for heterogeneous systems but lacks FPGA accelerator support. Our work presents a methodology making soft-core processors HSA compliant within MPSoC systems. This enables high level software programming and therefore eases the accessibility of soft-core FPGA accelerators. Furthermore, the integration effort is kept low by fully utilizing the HSA Foundation standards and toolchains.
