Abstract: A queue processor and its data processing method are provided. It can do high-speed data processing and decreases the electric energy consumption. The queue processor equips multiple operation data storing queues (18, 19) for storing the obtained memory stored data and intermediate result data during processing, and multiple execution units (17a, 17b, 17c) accessible to each of multiple operation data storing queues (18, 19), the execution unit (17a, 17b, 17c) doing the processing using memory stored data or intermediate result data obtained from any one of multiple operation data storing queues (18, 19), the execution units (17a, 17b, 17c) storing a calculated result in any one of multiple operation data storing queues (18, 19).

Abstract: A controlled flow parallel computer incorporating a node drive register which designates the location of executable instructions. The node drive register allows instructions to be executed concurrently and non-deterministically without a complex control.Control token locations in the node drive register associated with a given instruction are filled upon the completion of a prior instruction required to be executed before executing that instruction. The instruction is ready for execution once the control token locations are filled.

Abstract: A parallel processing computer comprises at least a memory for storing program as well as data and instructions for executing the program, a plurality of functional units, a node driving register for indicating executable instructions which are allowed to be executed by the functional units, and a mode register giving information to the functional unit as to whether the processing to be executed is of serial nature or parallel nature.
