VIRTUALIZATION IN A MULTI-CORE PROCESSOR (MCP) |
摘要 |
<p>This invention describes an apparatus, computer architecture, method, operating system, compiler, and application program products for MPEs as well as virtualization in a symmetric MCP. The disclosure is applied to a generic microprocessor architecture with a set (e.g., one or more) of controlling elements (e.g., MPEs) and a set of groups of sub- processing elements (e.g., SPEs). Under this arrangement, MPEs and SPEs are organized in a way that a smaller number MPEs control the behavior of a group of SPEs. The apparatus enables virtualized control threads within MPEs to be assigned to different groups of SPEs for controlling the same. The apparatus further includes a MCP coupled to a power supply coupled with cores to provide a supply voltage to each core (or core group) and controlling- digital elements and multiple instances of sub-processing elements.</p> |
