Microcontroller
Programmable device that performs computations and makes decisions based on program logic, central in controlling operations.
Sensors
Devices that collect data from the environment, such as temperature or speed, to be processed and used in decision making.
Actuators
Mechanical devices that move or control a mechanism, acting upon instructions from a control system to effect change in the environment.
Real-time Operating System (RTOS)
An operating system designed to manage hardware resources and host applications that run within deadlines, crucial for time-critical tasks.
Memory (RAM/ROM)
Storage areas in an embedded system where both the application code and the working data are stored.
Digital Signal Processors (DSPs)
Specialized microprocessors designed for high-speed numerical processing, ideal for signal processing applications.
Communication Interfaces
Hardware components like Ethernet, USB, CAN, which allow embedded systems to exchange data with external systems.
Analog-to-Digital Converters (ADCs)
Converts analog signals from sensors or other inputs into digital data that can be processed by microcontrollers.
Timers and Counters
Components for measuring time intervals, generating delays, or counting events, which are essential in timing control applications.
Digital-to-Analog Converters (DACs)
Converts digital output data from microcontrollers into analog signals, often to control actuators.
Power Supply
Provides regulated voltage and current to the embedded system components ensuring stable operation.
Field Programmable Gate Arrays (FPGAs)
Integrates configurable logic blocks that can be programmed for specific applications or functionalities, providing flexibility.
Interrupts
Signals that alter the processor's flow to handle events like input data ready or a timing event, ensuring real-time response.
Embedded Software
The specific code that runs on an embedded system's microcontroller to carry out its functions.
Watchdog Timer
Hardware mechanism that triggers a system reset or other corrective action if the system becomes unresponsive or behaves erratically.
