摘要
基于ARM的RISC处理器广泛应用于各种数字系统中.本文以AT91RM9200为系统平台,设计了一种基于双口RAM的实时数据接口,针对双口RAM的“乒乓”传输方式在Linux2.6下设计并开发了其驱动程序,最终实现了数据源与处理器间不间断、快速的数据传输。
RISC processors based on ARM are wildly used in various digital systems. This article took AT91RM9200 as system platform, and designed a real-time data interface based on dual-port RAM （DPRAM）, and also developed the driver for LintLx 2.6 to implement the ＂Ping-Pong＂ transmission of the DPRAM. Moreover, continues and fast data transmission between data source and processor was implemented.
