Multiple-Valued Programmable Logic Array with Application to Pipelined Signal Processing

With its low fabrication cost and high design flexibility. multiple-valued programmable logic array (MVL PLA) has been paid more attention to, recently. This paper will present a basic type of MVL PLA, show its dimention and its complexity. A comparison between different MVL PLA will be given and a general methodology for modular design using MVL PLA will be discussed as well. The paper then will demonstrate a detailed discussion of a pipelined image processing system and its implementation based on modular design using quaternary PLA. This quatenary PLA realization has some important advantages in processing hardware such as reduction in number of modules and interconnections between these modules while facilitate design procedure, thus encouraging new applications of MVL PLA and VLSI implementation for designing highly compact signal processors in advancing digital communication systems.
