Overview of this book

Modern and complex SoCs can adapt to many demanding system requirements by combining the processing power of ARM processors and the feature-rich Xilinx FPGAs. You’ll need to understand many protocols, use a variety of internal and external interfaces, pinpoint the bottlenecks, and define the architecture of an SoC in an FPGA to produce a superior solution in a timely and cost-efficient manner. This book adopts a practical approach to helping you master both the hardware and software design flows, understand key interconnects and interfaces, analyze the system performance and enhance it using the acceleration techniques, and finally build an RTOS-based software application for an advanced SoC design. You’ll start with an introduction to the FPGA SoCs technology fundamentals and their associated development design tools. Gradually, the book will guide you through building the SoC hardware and software, starting from the architecture definition to testing on a demo board or a virtual platform. The level of complexity evolves as the book progresses and covers advanced applications such as communications, security, and coherent hardware acceleration. By the end of this book, you'll have learned the concepts underlying FPGA SoCs’ advanced features and you’ll have constructed a high-speed SoC targeting a high-end FPGA from the ground up.

Introducing the Semi-Soft algorithm

The Semi-Soft algorithm idea isn’t new, and it has been around for many decades now since FPGA technology became prevalent in the electronics industry. It is a combination of hardware and software from the initial architecture development stages and is used to implement compute algorithms.

Using the Semi-Soft algorithm approach in the Zynq-based SoCs

When targeting a Zynq SoC, the hardware and software split between the PEs is considered from the start of the project rather than all the computing algorithms in the software being implemented, profiled, having the bottlenecks pinpointed (if any), and then hardware-accelerated. There is nothing wrong with the latter approach – it is just limiting in what can be achieved when targeting an ASIC technology to implement the design. Once the overall SoC architecture and microarchitecture have been defined, it is hard to modify the design at a later stage and introduce the optimal communication...
