(1) The data are loaded through simulating serial data transmission by I/O interface.

(2) The multi-tone interferences suppression in HF serial data transmission systems is analysed.

(3) Serial data transmission: In serial data transmission, bits are transmitted sequentially, one after the other.

(4) This system works according to the asynchronous serial data transmission protocol by programming a CPLD chip.

(5) This paper gives a serial transmission method which bases on the I2C BUS and its division. Wehave effectively solved the data delay in high speed serial data transmission system.
