    摘要: A programmable logic array comprising cells and a bus network in which the cells are arranged in a two-dimensional matrix of rows and columns and are interconnected by the bus network. The cells are also interconnected by a two-dimensional array of direct connections between a cell and its four nearest neighbors, one to its left (or to the West), one to its right (or to the East), one above it (or to the North) and one below it (or to the South). Each cell comprises eight inputs, eight outputs, means for multiplexing the eight inputs onto two leads and logic means that operate in response to the signals on the two leads to produce output signals which are applied to the eight outputs. The bus network comprises a local, a turning and an express bus for each row and column of the array and repeater means for partitioning said buses of a given row or column so as to form bus segments. The bus network provides for transfer of data to the cells of the array without using the cells as individual wires.

    摘要: A structured logic array is divided into hierarchical levels. At a highest level (the chip level), blocks are interconnected by a system of chip busses. A block interface couples each block to the chip bus system to allow the blocks to communicate with each other. At a lower level, each block includes sectors, each sector being coupled to a block bus system by a sector interface. The block bus system interconnects the sectors in each block to allow the sectors to communicate with each other. The block bus system is also coupled to the block interface to allow signals to be transferred between the block bus system and the chip bus system. At a lowest level, each sector includes a plurality of logic elements. The logic elements are interconnected by a sector bus system. The sector bus system is coupled to the sector interface to allow for the transfer of signals between the sector bus system and the block bus system.
