`
`An integrated control system design of portable computer

`
`Abstract
`
`This thesis mainly describes the design and realization of one particular
`integrated interface controller. The major purpose is to facilitate _the data
`retrieval and storage between computers with optional USB or IDE interface and
`
`all kinds of non-volatile storage memory cards ( MultiMediaCard, SmartMedia
`
`Card and CompactFIash card_ ) through a controller. And it provides ECC (Error
`Correction Code. ) function which simultaneously processes data during data
`
`transferring while automatically locating and correcting errors in an effective
`
`range of mistakes.The content of this thesis includes the regulation of the -
`specification for
`the integrated interface ' ' uuer,
`the illustration of the
`
`hardware design theory and methods for transfer interfaces concerning USB,
`IDE and non-volatile memory cards, and the way how to transfer data inma dual
`buffer mode in order to escalate the efficiency of data transferring. There is a
`
`single chip micro processor named 8051 in this integrated interface controller
`
`and the 8051 processor administrates the internal control register through
`external addressing, which monitors the signal protocol between hosts and
`interfaces , the selection of transfer interface of storage cards, and the switching
`on and off for logic circuit.
