AN APPARATUS AND METHOD FOR HETEROGENOUS CHIP MULTIPROCESSORS VIA RESOURCE ALLOCATION AND RESTRICTION |
摘要 |
<p>A method and apparatus for heterogeneous chip multiprocessors (CMP) via resource restriction. In one embodiment, the method includes the accessing of a resource utilization register to identify a resource utilization policy. Once accessed, a processor controller ensures that the processor core utilizes a shared resource in a manner specified by the resource utilization policy. In one embodiment, each processor core within a CMP includes an instruction issue throttle resource utilization register, an instruction fetch throttle resource utilization register and other like ways of restricting its utilization of shared resources within a minimum and maximum utilization level. In one embodiment, resource restriction provides a flexible manner for allocating current and power resources to processor cores of a CMP that can be controlled by hardware or software. Other embodiments are described and claimed.</p> |
