Preface
An MCU is a tiny chip-scale computer that integrates processor cores, memory, and various peripherals. MCUs are commonly used in control applications such as embedded systems, sensor control, automation, and more. They typically use a wider range of general-purpose computing power and rich peripheral interfaces.
DSP is a special chip designed for high-speed digital signal processing, and compared with MCU, DSP has powerful computing power, especially suitable for digital signal processing scenarios that require a large number of operations. DSP chips have a unique instruction set and are optimized for digital signal processing tasks, enabling them to meet a wide range of complex signal processing needs in real time.
With the development of the times, in order to meet the market demand for high performance and miniaturization, in recent years, many manufacturers have introduced MCUs with integrated DSP instructions. These integrated DSP-integrated MCUs combine the digital signal processing capabilities of a DSP with the general-purpose control capabilities of an MCU, providing engineers with a more flexible and efficient solution.
