Embedded System Design Based on SOPC Technology

As the improvement of computer architecture theory and the revolution of microelectronic technology,embedded technique got new progress,the research and application of which is currently hot technique.SOPC is a flexible,efficient SOC design methodology which is developed by Altera corporation.It can build a SOC design by integrating processor,memory unit,I/O and other peripherals selectively into a PLD.User defined logic can be added conveniently into SOPC design.This paper emphasis is to introduce design of embedded SOPC development board of Nios Ⅱprocessor core.
