摘要： A memory management unit (MMU) for a device controller that provides enhanced functionality while maintaining a small physical size or footprint, such that the die size required to manufacture the memory management unit circuitry within the device controller integrated circuit device remains small notwithstanding such enhanced functionality. This compact/tiny MMU provides virtual memory addressing and memory error detection functionality while maintaining a small physical die size. The small physical die size with enhanced functionality is obtained by improvements in translating virtual to physical addressing without use of extensive translation tables, which themselves would otherwise consume memory and associated die real estate. In addition, the MMU allows a firmware image containing code and data segments to be run-time swapped between internal shared context RAM and external memory.
摘要翻译：一种用于设备控制器的存储器管理单元（MMU），其在保持小的物理尺寸或占地面积的同时提供增强的功能，使得制造设备控制器集成电路设备内的存储器管理单元电路所需的管芯尺寸仍然很小，尽管具有这种增强的功能。这种紧凑型/微型MMU提供虚拟内存寻址和内存错误检测功能，同时保持较小的物理裸片大小。具有增强功能的小型物理尺寸通过改进虚拟到物理寻址的改进而获得，而不使用广泛的翻译表，其本身将消耗存储器和相关的裸片空间。此外，MMU允许包含代码和数据段的固件映像在内部共享上下文RAM和外部存储器之间进行运行时交换。

摘要： Methods and associated structures for bypassing virtual memory and memory mapping management features provided in a memory controller applied to simpler computing applications. In one aspect hereof, simpler, embedded computing applications may utilize standard memory controllers including cash management and memory component interfacing features but may bypass virtual memory management features within the same memory controller component. Rather, features and aspects hereof intercept memory accesses generated by the memory controller for address translation features and perform simpler address substitution to apply an appropriate translated address to the system bus.
摘要翻译：用于绕过存储器控制器中提供的虚拟内存和内存映射管理功能的方法和相关结构应用于更简单的计算应用程序。在一个方面，更简单的嵌入式计算应用可以利用包括现金管理和存储器组件接口特征的标准存储器控制器，但是可以绕过同一存储器控制器组件内的虚拟存储器管理特征。相反，其特征和方面拦截由存储器控制器产生的用于地址转换特征的存储器访问，并且执行更简单的地址替换以将适当的翻译地址应用于系统总线。
