  • Versatile and efficient cell-to-local bus interface in a configurable logic array
    Patent number: 5298805
    Abstract: A low transistor count programmable bussing resource for a programmable logic array allows the use of the bussing resources as inputs or outputs to a cell in the array and allows connections between different buses without effecting the normal use of the cell. The bussing resource allows efficient routing of signals between cells and is symmetric to allow rotation of logic macros built using combinations of cells and buses.

  • Diagonal wiring between abutting logic cells in a configurable logic array
    Patent number: 5296759
    Abstract: The present invention provides a configurable logic array that includes a plurality of individually configurable logic cells arranged in a matrix that includes a plurality of horizontal rows of logic cells and a plurality of vertical columns of logic cells. Adjacent abutting cells logic cells are interconnectable via horizontal and vertical configurable interconnections running between adjacent cells. Furthermore, configurable diagonal interconnections run between diagonally adjacent abutting logic cells in the array.
