Abstract: A reconfigurable processor array (RPA) for performing high speed operations on data arrays and eliminating I/O bottleneck. The array memory has a working side for storing arrays to be processed during a given array operation, and an I/O side for loading an array to be used during a subsequent operation and downloading an array resulting from a preceding operation.

Abstract: An alignment system for transferring only system words of a subarray embedded in an array in system memory between system memory and a buffer memory. The alignment system utilizes a parallel bus that transfers W system words per cycle and selects only subarray words for transfer between the system memory and the buffer. Additionally, a sequencer schedules and executes combinations of random and block accesses to mamximize bandwidth.

Abstract: A block processing computing system includes a decomposition unit, a control circuit, a system memory, a data block path and a block processor. The decomposition unit receives externally-supplied primitive command packets and decomposes the primitive into machine language operations on computational blocks of data. The control circuitry generates control and address signals for performing the machine level operations. The data block path includes alignment circuitry for selecting data from burst-accessed blocks of data and a macropipeline for controllably storing and transferring blocks of data to and from the block processor. The block processor has interchangeable, double-buffered local zone memories and a parallel set of pipelined vector processors for performing block operations on computational blocks of data.
