US Patent 7193438 Configurable integrated circuit with offset connection

Some embodiments of the invention provide an configurable integrated circuit (“IC”). This IC has at least fifty configurable nodes arranged in an array that several rows and columns. The IC also has several direct offset connections, where each particular direct offset connection connects two offset nodes that are neither in the same column nor in the same row in the array. In some embodiments, several direct connections do not include any intervening circuits. On the other hand, in some embodiments, several direct connections have intervening circuits, which differ from the nodes in the array.
