異質系統架構是一個為了支持廣泛資料平行和任務平行之程式模型的工業標準。現在，大多數支援異質系統架構的硬體和軟體仍在開發中，此時提供一個模擬環境給異質系統架構的開發者研發異質系統架構的軟體層將會很有幫助。本文提出一個異質計算模擬器框架，基於PQEMU和Multi2Sim的系統模擬器。該框架提供一個通用的介面，用以整合不同的模擬器，整個框架包含異質系統架構執行時期程式庫、異質系統架構圖形處理器之模擬器和中央處理器之模擬器。在我們初步的實驗中，異質計算模擬器框架已通過許多基準測試，可以幫助開發人員測試完整的軟體層和系統效能。

Heterogeneous System Architecture (HSA) is an industry standard designed to assist a wide variety of data-parallel and task-parallel programming models. Currently, most of HSA hardware and software components are either still in development. It is useful to provide an emulation environment for HSA developers in developing HSA software stacks. In this paper, we introduce the design of HSAemu framework, a full system emulator for the HSA platform, which is based on PQEMU and Multi2Sim. HSAemu framework provides a generic interface, which can integrate different simu-lator and emulator to HSAemu, the component of the framework including HSA runtime, HSA GPU emulator and CPU emulators. In our preliminary experiments, HSAemu framework already passed several benchmarks. It can help developers test-ing a complete HSA software stack and profile system performance.
