| Abstract: | 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. |
