Abstract: This paper considers IPX communication between 32 bits microcontroller ARM and DSPEC as the example, it is introduced detailedly, that the interface between RTL8019AS and ARM, and the design of RTL8019AS ethernet drive program, and data frame format and its meanings of IPX protocol, and packing program and unpacking program design of IPX communication based on ARM. The experiment result shows it has high speed and reliability, that ARM gets the block experiment data from DSPEC by the IPX communication, and the IPX communication is realized by the method for ARM.

Key words: 32 bits microcontroller ARM, IPX communication, RTL8019AS, DSPEC
