基于ARM芯片的PDA系统中硬件设计实现

Realization of Hardware Design in PDA Based on ARM

嵌入式PDA系统广泛应用于各个领域,为了设计一个高性能低成本的PDA系统,该设计利用ADS1.2开发环境开发基于ARM芯片的PDA系统,采用STR710芯片设计PDA硬件电路系统,利用坏块管理技术实现NAND_FLASH的存储管理,提高系统的整体性能,以及其在整体电路系统设计中外围芯片与CPU连接方式的可行性探讨,通过该设计很好地实现了预期目的,证实了系统采用ST公司的STR710芯片设计一套嵌入式PDA的可行性。

Embedded PDA system is applied in many fields widely. In order to design a high performance low cost PDA system. The design uses ADS1. 2 integrated development environment to design a PDA system based on ARM core. An embedded PDA hardware system is designed by adopting STR710 chip. NAND_FLASH memory manage is realized by bad block management to improve system＇s performance,connection feasibility of CPU to periphery chip is discussed. Anticipated goal is completed through the design. It confirms that using STR710 CPU to realize LCD＆NAND_FLASH function is possible and discusses the future work at last.
