MODULAR RE-CONFIGURABLE PROFILING CORE FOR MULTIPROCESSOR SYSTEMS-ON-CHIP

摘要

A modular dynamically re-configurable profiling core may be used to provideboth operatingsystems and applications with detailed information about run time performancebottlenecks andmay enable them to address these bottlenecks via scheduling or dynamiccompilation. As aresult, application software may be able to better leverage the intrinsicnature of the multi-corehardware platform, be it homogeneous or heterogeneous. The profilingfunctionality may bedesirably isolated on a discrete, separate and modular profiling core, whichmay be referred to asa configurable profiler (CP). The modular configurable profiling core mayfacilitate inclusion ofrich profiling functionality into new processors via modular reuse of theinventive CP. Themodular configurable profiling core may improve a customer's experience andproductivity whenused in conjunction with commercial multi-core processors.
