"Programmable logic has made it possible to create digital systems that are malleable, allowing for updates, changes, and enhancements on a chip that make digital systems cost effective and quickly available. - This book focuses on two types of this logic: field programmable gate arrays (FPGAs) and complex programmable logic devices (CPLDs). Critical insight is provided via detailed discussions, worked examples, and case studies of circuit design principles and common design decisions. - VHDL (VHSIC Hardware Description Language) is introduced and used throughout the book as it is used extensively in programmable logic."--BOOK JACKET
