Method for connecting system on programmable chip to Ethernet

Abstract

The invention relates to a method for connecting a system on programmable chip to an Ethernet, belonging to the technical field of electronic information. The method comprises the following steps: a DW8051 core is downloaded onto an FPGA chip to form a processor which is connected with an SFR decoding module through an SFR bus; the SFR coding module is connected with an SPI module which carries out data communication with a network chip through an SPI bus; the network chip transmits the data to the Ethernet or receives the data from the Ethernet through a network interface. The FPGA chip is aCyclone II EP2C20 chip of American ALTERA Company; the DW8051 core is a code module; the SFR coding module is a special functional register decoding module; the SPI module is a serial peripheral interface module; the model of the network chip is a W5100 chip of the Korea Wiznet Company. The model of the network interface is a common Ethernet interface RJ45. The method of the invention does not need to use hardware to describe an Ethernet networking module with complex language; the hardware is realized simply and conveniently, which shortens the development time of the products.

Description

technical field [0001] The invention relates to a method for connecting an on-chip programmable system to an Ethernet, and belongs to the technical field of electronic information. Background technique [0002] As the most widely used LAN technology at present, Ethernet has been used more and more in the fields of industrial automation, process control, and home intelligence by virtue of its advantages such as good openness, low cost, and high data transmission rate. At present, a large number of terminals that already exist, such as single-chip microcomputer systems and embedded systems, are connected to the Internet through Ethernet. [0003] With the development of integrated circuit technology, system-on-chip and programmable system-on-chip have been widely used in intelligent terminal systems. System on Chip (SOC: System on Chip) refers to the integration of a complete system on a single chip, integrating multiple IC chips into a single chip. With the further developm...
