Overview of this book

Modern digital devices used in homes, cars, and wearables contain highly sophisticated computing capabilities composed of embedded systems that generate, receive, and process digital data streams at rates up to multiple gigabits per second. This book will show you how to use Field Programmable Gate Arrays (FPGAs) and high-speed digital circuit design to create your own cutting-edge digital systems. Architecting High-Performance Embedded Systems takes you through the fundamental concepts of embedded systems, including real-time operation and the Internet of Things (IoT), and the architecture and capabilities of the latest generation of FPGAs. Using powerful free tools for FPGA design and electronic circuit design, you’ll learn how to design, build, test, and debug high-performance FPGA-based IoT devices. The book will also help you get up to speed with embedded system design, circuit design, hardware construction, firmware development, and debugging to produce a high-performance embedded device – a network-based digital oscilloscope. You’ll explore techniques such as designing four-layer printed circuit boards with high-speed differential signal pairs and assembling the board using surface-mount components. By the end of the book, you’ll have a solid understanding of the concepts underlying embedded systems and FPGAs and will be able to design and construct your own sophisticated digital devices.

Designing and implementing the FPGA algorithm

Up to this point, we have discussed only the details of the digital circuitry needed to receive an analog signal and perform the analog-to-digital conversion. We haven't really looked at what happens to an ADC sample after it has been captured. The next section will provide an overview of all of the functional elements of the digital oscilloscope system.

Digital oscilloscope system overview

Much of our work in the previous chapters has been focused on designing and constructing the hardware aspects of the digital oscilloscope add-on board that will plug into the Arty board. We will now examine the complete system at a high level.

The following figure provides a top-level view of the functional elements of the digital oscilloscope system:

Figure 9.1 shows the portions of the system that reside on the oscilloscope board, those on the Arty A7 board...
