Programmable Logic Devices and Configurable Logic Networks (PROGRAMMABLE LOGIC DEVICES AND CONFIGUARBLE LOGIC NETWORKS)

摘要

One or more logic combination networks (LCNs) can each be used to receive logic inputs from two or more PLDs (PLD1, PLD2) and provide inputs to programmable logic networks (POR, UCL, ...). By generating (O.P), it relates to a programmable logic device (PLD) and a configurable logic network to realize logic functions of various kinds and functions. Each programmable logic device has an input that receives signals A _x , B _x and an AND logic array (FAND ...) that generates a logic output signal and an input that receives a signal and outputs a logic output signal ( OR logic DFP generating OF ...) is provided with (OG ...). Either or both of the AND logic and OR logic arrays are programmable and these logic arrays are interconnected to apply an output signal from one of them as an input signal to the other array, the output from which is a PLD output signal. To provide. The logic combination network (LCH100) generates an output controlled by a set of programmable inputs (CN _x , DN _x ) to the generator as a function of the logic inputs (O, P) received from the programmable logic device. Or a programmable logic function generator (ULFG20, UBFF2P).
