FORTRAN IV simulator

Programs designed to functionally simulate execution of various host computer programs. Simulators are interpretive and provide bitforbit duplication of microprocessor instruction execution timing, register contents, etc. The system usually provides direct user control over execution conditions. RAM/register contents, interrupts, I/O data, etc.; 为模拟执行各种主计算机程序而设计的若干程序的总称。摸拟程序是解释性的程序, 可以产生微处理机指令执行时基、寄存器内容等的逐位复制内容。该系统通常让用户可以 直接控制运行情况、RAM或寄存器中的内容、中断、输入输出数据等。
