数字信号处理器(英文: Digital Signal Processor)是由大规模或超大规模集成电路芯片组成的用来完成数字信号处理任务的处理器。数字信号处理是将信号以数字方式表示并处理的理论和技术。数字信号处理与模拟信号处理是信号处理的子集。数字信号处理的目的是对真实世界的连续模拟信号进行测量或滤波。因此在进行数字信号处理之前需要将信号从模拟域转换到数字域，这通常通过模数转换器实现。而数字信号处理的输出经常也要变换到模拟域，这是通过数模转换器实现的。

Digital Signal Processor is a processor composed of large-scale or ultra large scale integrated circuit chips used to complete digital signal processing tasks. Digital signal processing is the theory and technology of representing and processing signals in a digital manner. Digital signal processing and analog signal processing are subsets of signal processing. The purpose of digital signal processing is to measure or filter continuous analog signals in the real world. Therefore, before performing digital signal processing, it is necessary to convert the signal from the analog domain to the digital domain, which is usually achieved through an analog-to-digital converter. The output of digital signal processing often needs to be transformed into the analog domain, which is achieved through a digital to analog converter.
