VLIW BASED VEX TOOL AND VALIDATION OF SIM-A WITH VEX

Abstract

There is a growing demand for application-specific embedded processors in system-on-a-chip designs. Current tools and design methodologies often require designers to manually specialize the processor based on an application. An application-specific instruction-set processor (ASIP) is a component used in system-on-a-chip design. The instruction set of an ASIP is tailored to benefit a specific application. This specialization of the core provides a trade-off between the flexibility of a general purpose CPU and the performance of an ASIC. The major contribution of this paper lies in verifying or substantiating SIM-A with VLIW based tool - Vex. Simulator SIM-A measures cycle count for application executed on processor. This paper discusses working with vex and its configuration required to execute the benchmark application on Vex.
