Abstract
Heterogeneous System Architecture (HSA) is an open industry standard that tightly coupled the CPU with variety accelerators and also designed to support data-parallel programming models. Although there is a HSA-compatible machine, it is still not the HSA fully supported machine. A lot of software components using HSA is in development, so it is useful by providing an emulation environment for verifying HSA software components and tool-chains In this paper, we introduce a HSA emulation platform that can support OpenCL 2.0, which is based on HSAemu framework. HSA emulation platform provides a plat-form that combines OpenCL 2.0 with Heterogeneous System Architecture, using Shared Virtual Memory in HSA to achieve the same feature in OpenCL 2.0, and sup-ply with other new features such as Generic Address Space, Device Enqueue, Pipe, C11 atomic. Programmers can verify whether the program written in OpenCL can leverage the Heterogeneous System Architecture. In our preliminary experiments, the HSAemu has been validated by those extra features mentioned above. It can help developers to verify the program results and performances.
