Study Notes
Embedded Systems Definition
- An embedded system is a system with software embedded into computer hardware.
- The software allows the system to be dedicated to a specific application or a specific part of a larger system.
- Embedded systems typically have a dedicated purpose and the software is usually embedded into a ROM or flash memory.
- An embedded system consists of a programmable computer that is not intended for general-purpose computing.
- An embedded system is an electronic system that contains a microprocessor or microcontroller, designed to perform one or a limited set of functions.
CPUs vs. MCUs vs. Embedded Systems
- Microprocessors (CPU) are typically defined as a single processor core that supports instruction fetching, decoding, and executing.
- Microprocessors can be used for general-purpose computing, but they need supporting memories and input/output (I/O) devices.
- Microcontrollers (MCU) typically have a single processor core, memory blocks, digital I/Os, analog I/Os, and other basic peripherals.
- Microcontrollers are typically used for basic control purposes, such as in embedded applications.
- Embedded systems are typically implemented using MCUs and often integrated into a larger mechanical or electrical system.
- Embedded systems typically have real-time constraints.
General Characteristics of Embedded Systems
- Embedded Systems are generally designed to perform one or a small set of functions.
- They are designed to dissipate low power.
- They have limited memory and limited peripherals.
- Applications are not meant to be altered by the user.
- They are highly reliable.
- Many embedded systems are not directly accessible, as they may be part of a larger system's control unit, so there is no interference with operation.
