CS/ECE 5780/6780: Embedded System Design

John Regehr

Lecture 1: Introduction to Embedded Systems
Embedded systems: denition

An embedded system is:

a special-purpose computer designed to perform dedicated functions often with real-time constraints. a system embedded as part of a complete system. really any system that is not a PC.although PCs contain several embedded systems.
Embedded systems: function

Five main categories:

Digital signal processing Control Networking User interfacing Data storage
Most embedded systems perform more than one of these functions.

Embedded systems design

Why is it unique?
Computation is subject to physical constraints such as timing deadlines, memory restrictions, and power consumption requirements. The traditional abstraction of separating software from the hardware and environment does not work. Hardware, software, and control are integrally intertwined. Designers must understand both hardware, software, and control. The Embedded Systems Design Challenge by Henzinger and Sifakis continues this discussion.

Top-Down Design Process

Analysis Phase
Discover the requirements and constraints. Requirements are general parameters that the system must satisfy. Specications are detailed, specic requirements. Constraints are limitations under which the system must operate.
Embedded system design metrics
Nonrecurring engineering cost Unit cost Size & weight Performance (accuracy, precision, resolution, response time, bandwidth) Power Flexibility, maintainability, reliability, testability, & compatibility Time-to-prototype Time-to-market Correctness Safety Look & feel

High-Level Design Phase

Build a conceptual model of the hardware and software system. Design broken into modules or subcomponents. Estimate cost, schedule, and expected performance. Develop a data ow graph for the system.
Data Flow Graph for a Motor Controller

Engineering Design Phase

Construct a preliminary design. This should include the hierarchical structure, basic I/O signals, shared data structures, and overall software scheme. Build mock-ups of mechanical parts and user software interface. Call graphs can be used to show how software and hardware interact.

Implementation Phase

During this phase, the design is actually built. Implementation of subcomponents may actually be started during the earlier phases. Debugging embedded systems can be very dicult. Therefore, extensive use of hardware/software simulation and cosimulation is essential.

Testing Phase

During this phase, we evaluate the performance. First, debug and validate the basic functions of the system. Next, evaluate and optimize various performance parameters such as execution speed, accuracy, and stability.

Maintenance Phase

During this phase, we:
Correct mistakes, Add new features, Optimize execution speed or program size, Port to new computers or operating systems, and Recongure the system to solve a similar problem.
Must be able to deal with changes in requirements or constraints. Not actually another phase, but more loops through the entire cycle.
