Embedded processors and controllers are specialized microprocessors and microcontrollers that are used in embedded systems. These are small, self-contained computer systems that are built into a larger device or system for a specific purpose, such as controlling a car engine or running a washing machine. Embedded processors and controllers are typically designed to be small, low-power, and highly efficient, in order to meet the specific requirements of the embedded system in which they are used.
Programmable logic devices, such as CPLDs and FPGAs, are integrated circuits that can be programmed to perform a wide range of digital functions. These devices are highly flexible and can be used to implement complex digital logic designs, such as those used in computer systems, telecommunications equipment, and industrial control systems. Unlike microprocessors and microcontrollers, which are typically pre-programmed to perform specific functions, programmable logic devices can be reconfigured to perform different functions as needed.
