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.

Kicking off the oscilloscope FPGA project

In this section, we will roll up our sleeves and get to work on an FPGA design project that will require the use of the FPGA development process discussed to this point, as well as a high-speed circuit board design, which we will get started on in the next chapter.

Project description

This project will develop a digital oscilloscope based on the Arty A7-100T board that uses a standard oscilloscope probe to measure voltages on a system under test. The key requirements of this project are as follows:

  • The input voltage range is ±10V when using a scope probe set to the 1X range.
  • The input voltage is sampled at 100 MHz with 14 bits of resolution.
  • Input triggering is based on the input signal rising or falling edge and trigger voltage level. Pulse length triggering is also supported.
  • Once triggered, up to 248 MB of sequential sample data can be captured. This data will be transferred to the host PC for display after...
