A hardware circuit that is used in address translation. 在地址转换中使用的一种硬件电路。
The development of multi-tasking application and architecture improvement introduce the need of virtual memory management in embedded processors. Virtual memory management is implemented through a hardware memory management unit ( MMU ) that supports address translation and protection on the fly. 随着体系结构的不断发展和多任务嵌入式系统的开发,嵌入式处理器需要提供虚拟内存管理的支持,虚拟内存管理是通过内存管理单元硬件实现在系统运行时的地址转换和地址空间保护。
Combined with the practice of hardware and software of local area network in their unit, Jianghan Geophysical Research Institute have built a safe and effective network system through adopting the technologies of network address translation and packet filtering. 江汉油田物探研究院结合本单位局域网硬件和软件的实际情况,采用网络地址转换和包滤波等技术构筑了一个安全有效的网络运行平台。
