Abstract

Heterogeneous System Architecture (HSA) is an architectural specification targeted at defining the coordination of devices. This chapter documents the design and implementation of three different HSA simulators, multi2Sim, HSAemu, and softHSA. These simulators offer various compromises between performance, debug ability, and platform fidelity to enable architecture research, ...
