A dsp and fpga ethernet loading method and signal processing system

Abstract

A kind of Ethernet loading method and signal processing system of DSP and FPGA, (1) make full use of the loading mode of DSP, realize remote Ethernet loading, after DSP loads successfully, feed back effective identification to remote host; (2) remote host receives DSP After the logo is successfully loaded, transmit the FPGA loading file to the DSP through the Ethernet, and the DSP transmits the received loading file to the FPGA through the GPIO interface, loads the FPGA in the form of Slave SelectMap, and feedbacks the effective logo to the DSP after the FPGA is successfully loaded; (3) After the loading is completed, the remote host will download system parameters (such as IP address and port number) to the DSP, and the DSP will configure its own IP address and port number according to the system parameters, and at the same time transfer the IP address and port number required by the FPGA through the EMIF bus. After the configuration is completed, the DSP and FPGA can communicate with the remote host through Ethernet. The Ethernet loading process method can realize remote loading of equipment, realize Ethernet communication between DSP and FPGA and a remote host, is suitable for the requirements of remote control and management of equipment, and has strong practicability.

Description

technical field [0001] The invention relates to an Ethernet loading method of DSP and FPGA and a signal processing system, belonging to the technical field of signal processing. Background technique [0002] There are various loading methods for DSP and FPGA. In most cases, it is self-starting through FLASH loading. The device does not need external devices to start, and it is relatively independent. However, there is a problem that it is inconvenient to update the loading file, and the loading file needs to be reloaded every time. Programming into FLASH, the flexibility is not enough. [0003] The system application mode includes remote control or unattended mode. In the above mode, the operator is far away from the DSP and FPGA hardware, and can only operate through the remote host. In this case, it is difficult to update the DSP and FPGA loading files through other loading methods. , It is necessary to additionally use a loading cable and a computer to program the loadin...

[0002] There are various loading methods for DSP and FPGA. In most cases, it is self-starting through FLASH loading. The device does not need external devices to start, and it is relatively independent. However, there is a problem that it is inconvenient to update the loading file, and the loading file needs to be reloaded every time. Programming into FLASH, the flexibility is not enough

[0003] The system application mode includes remote control or unattended mode. In the above mode, the operator is far away from the DSP and FPGA hardware, and can only operate through the remote host. In this case, it is difficult to update the DSP and FPGA loading files through other loading methods. , it is necessary to additionally use the loading cable and computer to burn the loading file into the FLASH memory, the burning process is slow, and the cost of manpower and material resources is high
