SDRAM是具有高速缓冲功能的存储器,本设计将其应用在楼宇智能化的自动化监控系统中,这样控制室即可对大楼情况进行实时监控。文章重点介绍了SDRAM的模块化切换设计,不仅加大了SDRAM的调用灵活度,而且利用切换功能提高了SDRAM的利用率,增加了吞吐量。 SDRAM is a cache with a cache memory, the design will be applied to the intelligent building automation monitoring system, so that the control room can be real-time monitoring of the situation in the building. This article highlights the SDRAM modular switching design, not only increased the flexibility of SDRAM call, and the use of switching capabilities to improve the utilization of SDRAM and increase throughput.
