Programmable Logic Circuit Design

Abstract

Programmable logic circuit (PLC) has the advantages of high flexibility, short development cycle, and strong scalability. It is widely used in communication, industrial control, military, and other fields. This chapter focuses on the PLC design technology. Firstly, it introduces the main categories and functional characteristics of PAL, GAL, complex PLD (CPLD), and FPGA. After that, the hardware description language, system structure, storage mode, and other core technologies of the representative programmable logic devices (PLD), such as field programmable gate array (FPGA), electrical programmable logic device (EPLD), and programmable system chip, are analyzed. Finally, the main advantages and technical features of the state-of-the-art reconfigurable computing chips in this field are introduced.
