Abstract:

Modern signal processing design that has often been used in signal processing board between host computer and data communications, DSP embedded device access Ethernet has become a new research field at present. The paper introduced a new type of 10/100 M Ethernet control chip W5300,and in underwater acoustic signal processing card system design based on W5300 embedded DSP data transmission hardware interface,prepared by NIC driver. Proved by the experiment achieved the design aim,through Ethernet,it can be gotten that remote,fast data transmission and storage and meet the requirements of underwater acoustic detection signal processing card work.

Conclusion:

This article mainly explains the design and implementation of the Ethernet control chip W5300 in the underwater acoustic signal processing card, and uses C language to write the Ethernet chip W5300 driver program. The code is compiled and passed on the CCS3.3 compiler, realizing the embedded The equipment's access to Ethernet solves the problem of network communication between DSP and PC, and provides a new transmission method and approach for communication between the underwater acoustic detection signal processing card and the host computer PC.
