A digital signal processor (DSP) is a specialized microprocessor designed to efficiently process and manipulate digital signals. These signals can include audio, video, and other data types, allowing for tasks such as filtering, compression, and analysis. DSPs are widely used in various applications, including telecommunications, audio processing, and image processing. DSPs are optimized for high-speed mathematical operations, making them ideal for real-time processing. They often feature dedicated hardware for tasks like multiplication and addition, which enhances their performance compared to general-purpose processors. This efficiency enables devices like smartphones, cameras, and medical equipment to deliver high-quality results.
