一、显示和键盘管理按照一般的惯例,设计用于控制的微机系统可按下述步骤进行: 1) 分析任务,列出功能清单,设计出控制流程图。 2) 在全面综合分析任务对系统硬、软件要求后,选定系统结构:它在处理速度上应能满足系统要求,确定采用单机或多处理机结构,所选用的处理器及存贮器、通道接口、外设、中断系统等。 3) 按照对成本的要求及设计者的编程能力等因素来确定硬、软件的比例关系,在配合上要相辅相成。 4) 完成样机设计后,进行现场或模拟的调
First, the display and keyboard management In accordance with the usual practice, designed for control of the computer system can be carried out according to the following steps: 1) analysis tasks, lists the function list, design control flow chart. 2) After a comprehensive and comprehensive analysis of the system hardware and software requirements, select the system structure: it should be able to meet the system requirements in processing speed, to determine the use of single or multi-processor structure, the selected processor and memory, Channel interface, peripherals, interrupt system. 3) In accordance with the requirements of the cost and the designer’s programming ability and other factors to determine the proportion of hardware and software, in cooperation with each other to complement each other. 4) After the completion of the prototype design, the scene or simulated tune
