软件是指程序与开发、使用、维护程序所需的全部文件等。软件的研制过程基本上分三步进行:首先编制源程序;其次是使程序变换成目标程序;然后进行程序调试,最后把程序存在贮器中。一、设计原则生产过程控制是实时拉制系统,其软件的速度、容错和价格都是保证系统可靠性的重要因素。执行速度快,可以节省微处理器更多 Software refers to programs and all the files needed to develop, use, and maintain programs. The software development process is basically divided into three steps: First, the source program is compiled; secondly, the program is transformed into the target program; then the program is debugged, and finally the program is stored in the reservoir. First, the design principle The production process control is the real-time drawing system, its software speed, the fault tolerance and the price are the important factors that guarantee the system reliability. Fast execution saves more microprocessors
