Abstract
A cell broadband engine processor includes a memory a power processing element (PPE) coupled with the memory, and a plurality of synergistic processing elements. The PPE creates a SPE as a computing SPE for an application. The PPE determines idles ones of the plurality of SPEs, and creates an idle one of the plurality SPEs as a managing SPE. Each of the plurality of SPEs is associated with a local storage. The managing SPE informs the computing SPE of a starting effective address of the local storage of the managing SPE and an effective address for a command queue. The managing SPE manages movement of data associated with computing of the computing SPE based on one or more commands associated with the application. A computing SPE sends the one or more commands to the managing SPE for insertion into the command queue.
