Additionally, the report introduces the CacheBench benchmark, which is designed to assess the memory hierarchy performance of computer systems, with a specific focus on parameterizing the performance of multiple cache levels on the processor. The performance metrics are measured in terms of raw bandwidth in megabytes per second, with a particular interest in the cache's ability to sustain large, unit-stride, floating-point workloads. The report also delves into a discussion of cache architecture, emphasizing their small size and high-speed nature. This initial draft serves as a comprehensive introduction to essential security and trust concepts as well as a performance benchmarking tool for computing systems.
