Structured Accelerator Design: Patterns for High-Level Synthesis

Accelerators now play a crucial role in computing systems. With the emergence of a new wave of academic and industrial high-level synthesis (HLS) tools, FPGA-based accelerators now are more accessible to software programmers. However, there are several burdens placed upon the programmers to design a high-performance accelerator when using FPGA, such as different memory and parallel programming models. Therefore, a high-level structured design approach targeting accelerator is essential. This approach advances software programming techniques to utilise FPGAs efficiently.This book explains the concept of accelerator design using current high-level synthesis tools and techniques. It describes different types of regular and irregular accelerator patterns as a structured building block for FPGA implementation.The cutting-edge programming models based on C/C++ and OpenCL are used to explain standard computation and memory patterns through many examples and case studies.In short, this book•offers theory and practice of HLS parallel programming techniques for FPGA•describes parallel patterns for regular and irregular algorithms•contains detailed examples in C/C++ and OpenCL for HLS•represents the efficiency of FPGA accelerators through several case studies in scientific computation and machine learning areas
