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. The array further includes at least one horizontally aligned express bus running between adjacent rows of logic cells, the logic cells in the adjacent rows being connectable thereto, and at least one vertically aligned express bus running between adjacent columns of logic cells, the logic cells in the adjacent columns being connectable thereto. The array further includes at least one generally diagonally aligned local and/or express bus running between adjacent diagonally aligned logic cells, the adjacent diagonally aligned logic cells being connectable thereto.
