Embodiment
[0031] A method for connecting a programmable system on a chip to an Ethernet, the system block diagram is as follows figure 1 As shown, the DW8051 core 2 is downloaded to the FPGA chip 1 to form a processor. The processor is connected to the SFR decoding module 3 through the SFR bus. The SFR decoding module 3 is connected to the SPI module 4. The SPI module 4 is connected through the SPI bus. Perform data communication with the network chip 5, the network chip 5 transmits data to the Ethernet 7 or receives data from the Ethernet 7 through the network interface 6, so as to realize the communication between the on-chip programmable system and the Ethernet.
[0032] The FPGA chip 1 is a field programmable gate array, and the model is the Cyclone IIEP2C20 chip of the American ALTERA company.
[0033] The DW8051 core 2 is a code module, which is an IP core in the Design Ware library of the American Synopsys company.
[0034] Described SFR decoding module 3 is special function reg...
