Abstract: A cache class in a software-administered cache of a multiprocessor is assigned cache space that is localized to a single region of a memory and is contiguous. Synchronization and LRU operations can step sequentially through the given region, removing the need for SLB searches or the penalty for a miss, while other threads remain random access. The threads that manage each virtual memory area can then be attached to specific processors, maintaining physical locality as well.

Abstract: A method and apparatus for processing a bi-directional dataflow are disclosed which permits the transparent movement of data from one processor to another via a shared memory fabric which is connected with both processors. This permits the incoming data of a first processor to be utilized by a second processor thereby freeing that processor from having to handle incoming data. Further, the second processor can handle outgoing data exclusively, freeing the first processor from having to handle outgoing data. In this way, each direction of a bi-directional dataflow may be handled by the maximum capability of a bi-directional capable processing device. The shared memory may comprise a plurality of banks of synchronous dynamic random access memory (SDRAM) devices, and may be used to store packet data in a network.

Abstract: A method and apparatus to strengthen an individual hands, fingers and wrists includes at least one resilient band supported by at least one of a plurality of spaced pegs which extend from at least one side of a support base and wherein resistance of the at least one resilient band to manipulation by the fingers and hands is used to exercise and strengthen muscles of the hands and wrists.
