Abstract
Among other things, the disclosure is applied to a generic microprocessor architecture with a set (e.g., one or more) of controlling/main processing 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 using program code embodied as a set of virtualized control threads. The apparatus 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. In accordance with these features, virtualized control threads can traverse the physical boundaries of the MCP to control SPE(s) (e.g., logical partitions having one or more SPEs) in a different physical partition (e.g., different from the physical partition from which the virtualized control threads originated.
