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

摘要

A modular dynamically re-configurable profiling core may be used to provide both operating systems and applications with detailed information about run time performance bottlenecks and may enable them to address these bottlenecks via scheduling or dynamic compilation. As a result, application software may be able to better leverage the intrinsic nature of the multi-core hardware platform, be it homogeneous or heterogeneous. The profiling functionality may be desirably isolated on a discrete, separate and modular profiling core, which may be referred to as a configurable profiler (CP). The modular configurable profiling core may facilitate inclusion of rich profiling functionality into new processors via modular reuse of the inventive CP. The modular configurable profiling core may improve a customer's experience and productivity when used in conjunction with commercial multi-core processors.
