Embedded Programmable Logic Devices (PLDs) are versatile electronic components used in a range of digital circuits, offering a customizable solution for various applications. Essentially, these are Integrated Circuits (ICs) that users can configure to perform specific logic functions. Their main function is to control digital operations within electronic devices, based on the programmed logic that has been embedded into them. The programmability of these components means they can be used in different configurations, allowing for flexibility and adaptability in design and function. PLDs are particularly useful in situations where changes to the digital logic may be required after the hardware has been manufactured, making them indispensable in prototyping and iterative development processes.
The PLDs are commonly used in applications that require complex logic operations, such as automotive systems, telecommunications, consumer electronics, and data processing. The characteristics that make these components highly sought after include their reprogrammability, which enables modification and updating of the device without needing to replace hardware, and their ability to perform multiple functions which save space and complexity in circuit designs. High-speed performance and power efficiency are also hallmark features of modern PLDs. Notable manufacturers in the industry producing Embedded PLDs include Xilinx, Altera (now part of Intel), Lattice Semiconductor, and Microchip Technology. These manufacturers lead the market, providing a range of PLDs to suit various levels of complexity and performance requirements.
