Abstract: The ecological construction of microprocessor chips is the key to the autonomy and controllability of highend equipment and intelligent microsystems. Although the domestic digital signal processing (DSP) devices and their related development and application technologies have been developed in recent years, there is still a large gap with the demand; in the field of active noise control, the feed-forward multi-channel control scheme effect has a larger control range and better performance than single channel, but has higher requirements on the computing power of the system In this paper analyzes the computing power of the multi-channel noise reduction system based on the multi-channel FxLMS algorithm is analyzed, and a control system scheme based on the circuit structure of a domestic DSP development board is designed and conducts an experimental study is conducted. The results show that the designed noise control system has 80% higher computing efficiency than ARM as an operator, and the attenuation of the periodic noise signal within 100-1 000 Hz reaches 15-20 dB, which proves the correctness of the scheme.
