This book combines traditional teaching approach with the use of mathematics, along with the use of hardware description language and processor of concrete as a vehicle for "hands-on" modeling and experimenting with digital logic and design of the processor. Features: includes extensive introductory chapter, outlining the basic method to evaluate the processor; investigate advanced topics in the design of the processor; presents detailed description of the tool-chain development; provide stand-alone tutorial on using SPIM; focus on the aspect compiler closely with processors, exploring the concept of efficient programming; concludes each chapter with a set of example problems.
