基于SOPC技术的嵌入式系统设计

Embedded System Design Based on SOPC Technology

随着计算机体系结构理论的完善以及微电子工艺技术的革新,嵌入式技术不断取得新进展,其研究和应用已成为当前的热门技术.SOPC是Altera公司提出的一种灵活、高效的片上系统设计方案,它可以有选择地将处理器、存储器、I/O等系统设计需要的组件集成到一个PLD器件上.在SOPC设计中可方便地加入用户自定义逻辑.重点介绍基于NiosⅡ内核处理器的嵌入式SOPC开发板的设计.

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 Ahera 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 II processor core.
