Abstract
An integrated circuit including a programmable logic array with a plurality of logic cells and programmable interconnections to receive input signals and to perform logical functions to transmit output signals. The integrated circuit may also include megacells comprising a plurality of functional blocks receiving inputs and transmitting outputs. The integrated circuit may also include a programmable interconnections subsystem to cascade the megacells. The megacells are coupled to the programmable logic array.
