Abstract

In this work a Virtual Platform (VP) is presented containing a novel processor model for the latest ARMv8 instruction set architecture. This processor model was constructed using the Unicorn emulator [6]. The necessary modifications to the Unicorn emulator and subsequent performance improvements during SystemC simulation are shown in detail. In addition the integration into a VP using a state-of-the-art SystemC modeling library is described. A comparison is made with a VP containing another similar processor model, highlighting the benefits of using Unicorn for processor modeling in a SystemC environment.
