基于ISA总线的高码速率大容量遥测数据存储器的研究

Research on High Bit Rate and Large Scale Telemetry Data Memorizer Based on ISA Bus

介绍基于 ISA(Industry Standard Architecture)总线的高码速度大容量遥测数据存储器的研究。作为计算机主存储设备的硬盘 ,它具有体积小 ,存储容量大的优点 ,本系统拟采用硬盘作为存储设备 ,且遥测数据在存储数据时采用脱线工作方式 ,我们设计了该存储器和计算机的接口且实现了对硬盘传输数据的 PIO(Program Input Output)

In this paper,the research on a high bit rate and large scale telemetry data memorizer based on ISA bus is introduced.The adoption of a hard disk as the main memorizer of a computer will be possessed of some merits such as small volume and large memory capacty.In the design of this system,a hard disk is adopted as the main memorizer.When data are stored ,the data memorizer is operated with off line mode.The design of the interface of data memorizer with computer,and the implementation of the PIO (Program Input Output) programming are presented in this paper.
