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.
