Abstract:

This paper describes the sequence analysis on powering, modeling of Finite State Machine and realization of Finite State Machine, introduces the transfer model from SPI bus to LPC bus by emulating sequence circuit in detail, based on entire selection and entire design and by researching the embedded controller and CPLD. And then it realizes Power Management and the connection between embedded controller and host.

Key words: CPLD, Finite State Machine(FSM), embedded contoller
