摘要
介绍了双端口随机存储器(以下简称“DPRAM”)芯片IDT7133的外部管脚功能及其芯片特点。针对多处理器系统中的数据存储与共享问题,着重阐述了基于普通单口RAM和基于DPRAM芯片IDT7133两种不同的多处理器系统应用方案。通过对两个方案的比较,认识到基于DPRAM芯片IDT7133的应用方案在数据共享及数据传输中的显著优势。最后还谈到了IDT7133芯片内部的数据存储方式,为该方案在现实中的合理运用提供了保证。
This article introduced a dual-port random access memory monolithic chip-IDT7133, including its external pin configurations and characteristic. As to data storage and share, it interprets two different examples of multiprocessor application; one is based on normal single-port RAM and the other is based on DPRAM-IDT7133. The latter example has got the obvious advantage of data share and transmission in multiprocessor application compared with the former one. Data storage method inside IDT7133 is fully described so as to ensure proper practical application.
