  • Patent number: 4831577
    Abstract: The invention performs the multiplication and/or accumulation of digital numbers in either two's complement of unsigned magnitude representation. A modified Booth algorithm minimizes the number of partial products generated. Two adder arrays sum the partial products in parallel to generate intermediate values which are then summed by a third adder array. The partial products are divided between the two adder arrays in a manner which optimizes the speed of the circuit.

  • Patent number: 4787047
    Abstract: A programmable logic gate array employing a plurality of reprogrammable fuses having a logical NAND characteristic for logically connecting selected inputs to selected logic gates. The fuses are selectively programmed for providing appropriate signals to allow three modes of operation of the logic gate array; programming, erasure and normal logic operation.

  • Patent number: 4644353
    Abstract: A programmable interface to selectively couple the terminals of an electronic system to desired circuit locations within the system. By applying programming signals to the input terminals of the interface in a prescribed sequence, the interface is programmed so that subsequently applied control signals will be coupled to the desired circuit locations. The function served by each terminal thus depends on the programming sequence. Reprogramming can change the function of each of the terminals by coupling them to different circuit locations.
