Technical details and manufacturing context for Digital Signal Processor (DSP)

Definition
A Digital Signal Processor (DSP) is a specialized microprocessor chip designed to perform high-speed, numerically intensive calculations on digitized signals. As a core part of Signal Processing Circuitry, it executes algorithms for filtering, compression, modulation, and analysis of audio, video, sensor, and communication signals with high efficiency and low latency.
Working Principle
The DSP receives analog signals converted to digital data via an ADC. It processes this data stream using optimized arithmetic logic units (ALUs), hardware multipliers, and specialized instruction sets to execute signal processing algorithms (e.g., FFT, FIR filters) in real-time. Processed digital data can then be output directly or converted back to analog via a DAC.
