Patent ID: 7965102

Claim:
An integrated circuit, comprising: circuitry, the circuitry being arrayed in columns, the columns of circuitry being oriented in a principal direction and one or more of the columns of circuitry is enabled to be associated with a columnar programmable device, wherein the circuitry comprises input/output circuits arranged to form only substantially parallel columns of input/output circuits within the integrated circuit along, at most, two parallel edges of the integrated circuit having a same orientation as the columns of input/output circuitry: wherein at least one column of the columns of circuitry comprises an application specific circuit; the application specific circuit being associated with instantiation of a predetermined design in the columnar programmable device; the at least one column being associated with the instantiation of at least a portion of the predetermined design in the columnar programmable device; the at least one column being associated with a configurable column of the columnar programmable device; and wherein the application specific circuit is implemented in place of a column that is unused by a user design instantiated within the integrated circuit.
