ABSTRACT:
Disclosed is an integrated circuit having multiple programmable arrays providing customizable logic. The integrated circuit has at least a first programmable array receiving a plurality of first inputs and generating a plurality of first outputs as programmed by the user. Also, it includes a second programmable array receiving a plurality of second inputs and generating a plurality of second outputs as programmed by the user. A means for selectiving interconnecting the inputs and outputs from the first and second programmable arrays is provided so that the programmable signals generated can be selectively connected in series, in parallel, or in a combination of series and parallel. Also provided are buried state registers for storing signals as programmed by the user. The stored signals from the buried state registers are likewise selectively interconnected with the input signals and output signals to provide added flexibility and power for the logic designer utilizing the device of the present invention.
