Abstract: A computing device, a communication/synchronization path or channel apparatus and a method for parallel processing of a plurality of processors. The parallel processing computing device includes a first processor having a first central processing unit (CPU) core, at least one second processor having a second central processing unit (CPU) core, and at least one communication/synchronization (com/syn) path or channel coupled between the first CPU core and the at least one second CPU core. The communication/synchronization channel can include a request message queue configured to receive request messages from the first CPU core and to send request messages to the second CPU core, and a response message queue configured to receive response messages from the second CPU core and to send response messages to the first CPU core.

Abstract: A method for managing object-oriented queues by reusing queue entry objects instead of creating and destroying each queue entry object inserted into and removed from the queue. Inserting a queue entry object into the queue involves changing the status of the queue entry object from available to in-use, adding the queue entry object to a queue list, returning a reusable queue entry object to the queue user, receiving an insertion notification that the queue entry object data is valid, and marking the insertion of the queue entry object into the queue as complete. Removing a queue entry object from the queue involves un-marking the queue entry object in the queue as complete, removing the queue entry object from the queue list, returning the valid queue entry object to the queue user, receiving a removal notification that valid data has been extracted from the queue entry object, and changing the status of the reusable queue entry object removed from the queue list from in-use to available.

Abstract: As copies of data from a main memory are stored in a cache memory of a processor of a computer system as original data, the addresses of those copies are stored successively in a queue. Once the depth of the queue is reached, the storage of each new address in the queue causes a previously stored address to be output from the queue. For each address output from the queue, the corresponding original data in the cache is returned to the main memory. The amount of original data stored in the cache is therefore limited. Preferably, the queue comprises a first-in, first-out queue, and the depth of the queue is programmable.
