Book Overview

This book is intended to teach anyone, either someone with deep hardware development skills, or someone with little prior hardware design knowledge alike to learn how to design and verify dedicated hardware modules using HLS. HLS converts untimed or partially timed behavioral descriptions into efficient hardware descriptions in either Verilog or VHDL that can in turn be further synthesized into gate netlists through logic synthesis. The word efficient is extremely important as nobody would build a integrated circuit (IC) using HLS if the generated circuit is larger, slower and consumes more power than using traditional methods based on low-level Hardware Description Languages (HDLs).

The book will start by describing what HLS is and its main benefits. It will then cover the theory behind HLS. Basically I will answer the question of how an untimed behavioral description that was originally intended to be compiled to machine code to be executed by a Central Processing Unit (CPU) is converted into a dedicated hardware unit. The book will cover different types of optimizations to allow the designer to generated the hardware circuit within the intended constraints, and finally it will cover different input languages and how they differ. In particular ANSI-C and SystemC. I share this book with the hope that you might find it useful. Happy reading.

Benjamin Carrion Schaefer

Dr. Carrion Schaefer has over 20 years of academic and industrial experience in the design of hardware systems, FPGA and ASICs as well as in the development of commercial HLS tools. From 2007 to 2012 he was a member of the NEC teams that developed NEC's HLS tool CyberWorkBench. He recently created highX Technologies. A company dedicated to making hardware design easier by providing highly customizable Behavioral IPs for High-Level Synthesis.

He currently serves as associate Professor at The University of Texas at Dallas at the department of Electrical and Computer Engineering (ECE) where he has established the Design and Reconfigurable Computing Laboratory (DARClab). At UTD he investigates how to leverage the advantages of using of High-Level Synthesis (HLS) instead of traditional hardware decription languages such as Verilog or VHDL, and how to address new issues that arise when using HLS. He also served multiple years at OSCI's (now Accellera's) SystemC synthesizable subset working group as one of the members drafting the latests draft (version 1.4).

The author, holds a Ph.D. from The University of Birmingham, UK and an MBA from McGill University, Canada.
