FPGA Prototyping by VHDL Examples

An introductory text, this book introduces the HDL (hardware description languages) and FPGA development process to designers through a series of hands on experiments. The main focus of the book is on the effective derivation of hardware.

A hands-on introduction to VHDL synthesis and FPGA prototyping Hardware Descriptive Language (HDL) and Field Programmable Gate Array (FPGA) devices allow designers to quickly develop and simulate a sophisticated digital circuit, realize it on a prototyping device, and verify the operation of its physical implementation. As these technologies have matured, they have become accepted mainstream practice so that it is possible to use a PC and an inexpensive FPGA prototyping board to construct a complex digital system. This book uses a "learn by doing" approach to introduce the concepts and techniques of VHDL and FPGA to designers through a series of hands-on experiments. FPGA Prototyping by VHDL Examples provides: A collection of clear, easy-to-follow templates for quick code development A large number of practical examples to illustrate and reinforce the concepts and design techniques Realistic projects that can be implemented and tested on a Xilinx prototyping board A thorough exploration of the Xilinx PicoBlaze soft-core microcontroller Although the book is an introductory text, the examples are developed in a rigorous manner and the derivations follow strict design guidelines and coding practices used for large, complex systems. It lays a solid foundation for students and new engineers and prepares them for future development tasks. FPGA Prototyping by VHDL Examples is an indispensable companion text for introductory digital design courses and also serves as a valuable self-teaching guide for practicing engineers who wish to learn more about this emerging area of interest.
