    Study Notes

    Embedded Systems: Introduction

    • An embedded system is a combination of computer hardware and software, designed to perform a specific function within a larger system.
    • Embedded systems often integrate with general-purpose computers, but can sometimes be built without a dedicated processor or software.

    Real-Time Systems

    • Real-time systems operate with timing constraints, meaning they must perform calculations or decisions within specific deadlines.
    • The deadline for a real-time system can vary, from milliseconds to hours.

    Common Components of an Embedded System

    • Processor: executes the software instructions.
    • Software: includes the program instructions that control the embedded system.
    • Memory:
      • RAM (Random Access Memory): temporary storage for active data and programs.
      • ROM (Read Only Memory): stores permanent data and programs.
    • Inputs and Outputs: allow the embedded system to interact with the surrounding environment.

    Requirements Influencing Design Choices

    • Processing Power: Determined by the workload the processor can handle, often measured in MIPS (millions of instructions per second).
    • Memory (ROM & RAM): Amount required to store the executable program and data it processes.
    • Number of Units (Production Run): Impacts manufacturing costs and design choices.
    • Power Consumption: How much power is used during operation, often measured in mW/MIPS (milliwatts per MIPS) for portable devices.
    • Development Cost: Costs incurred for hardware and software design, referred to as NRE (nonrecurring engineering).
    • Lifetime: Expected duration of the product’s use.
