A case for I/O response benchmarking of microprocessors

The main goal of this paper is to describe a new methodology to evaluate the I/O responsiveness of microprocessors. This addresses the need for benchmarks for real-time systems that measure critical properties for system design that are not currently handled by traditional performance benchmarks. The benchmark developed under this methodology is tested on three microprocessor architectures: ARM, PIC and XMOS. The results of the benchmarks show that the response latency of systems can vary significantly between architectures and under different system loads.
