Abstract
Methods and apparatus for gathering information from processors by using compressive sampling are presented. The invention can monitor multicore processor performance and schedule processor tasks to optimize processor performance. Using compressive sampling minimizes processor-memory bus usage by the performance monitoring function. An embodiment of the invention is a method of gathering information from a processor, the method comprising compressive sampling of information from at least one processor core. The compressive sampling produces compressed information. The processor comprises the at least one processor core, and the at least one processor core is operative to process data.
