| 释义 | emulator vs. simulator 仿真程序与模拟程序的对比;［模仿程式与模拟程式的对比］ In a basic sense, emulation means the modification of a compu ter system to execute programs that are written for another system. This modification may consist o f the addition of software, microprograms,or hardware. Historically, an emulator has been used as support during the trans itional period of converting or upgrading one data processing system to another. Whereas, an emulator uses added microprograms or hardware, a simulator uses only the software of the host machine to simulate ins tructions of the machine to be realized. 就基本意义而言,仿真意味着修改计算机系统,以执行为另一个系统所写的程序。这种修改可 由附加软件、微程序或硬件组成。历来,在一个数据处理系统转换或升级为另一个系统的过渡时期, 仿真程序是一种支持手段。另一方面,一个仿真程序使用附加的微程序或硬件,而模拟程序只用主机的软件来模拟被执行的机器指令 |
