Digital Signal Processor

A specialised microprocessor designed to perform mathematical operations on digital signals in real time, such as filtering, compression, and pattern recognition. In assistive technology, DSPs are used in hearing aids to process and amplify sound, in speech recognition systems, in Braille translation devices for real-time optical processing, and in other devices where sensor data must be analysed and acted upon with minimal latency. Their efficiency at repetitive numerical computations makes them well-suited for portable assistive devices where processing power and battery life are both critical.
