摘要:A programmable logic device (PLD) and configurable logic network in which oneor more logic combination networks (LCN) each receives logic inputs from two or morePLDs (PLD1, PLD2) and generates logic outputs (O, P) which provide inputs toprogrammable selectors (POR, UCL, . . . ) for controlling implementation of logicfunctions of various types and functionality by a controllable logic function sub-networkby routing through the sub-network, logic values and logic instructions originatingexternally of the PLD's. Each programmable logic device includes an AND logic array(FAND . . . ) having inputs for receiving signals (Ax, Bx) and generating product termoutput signals and an OR logic array (OG . . . ) having inputs for receiving signals andgenerating sum term output signals (OF . . . ). One or both of the AND logic and OR logicarrays is programmable and the logic arrays are interconnected to apply output signalsfrom one of them as input signals to the other one, the output from which provides PLDoutput signals. The logic combination networks may be fixed logic networks (LCN100) orprogrammable logic function generators (UBLFG2O, UBFF2P) that produce outputscontrolled by a set of programmable inputs (CNx, DNx) to the generator as a function ofthe logic inputs (O,P) received from the programmable logic devices.
