Abstract
An embedded device and a memory management method of the embedded device are provided. The embedded device includes a system memory and hardware memory. An operating system of the embedded device operates based on virtual memory addresses. The method includes: mapping the virtual memory addresses to indirect memory addresses by a first memory management unit; and mapping the indirect memory addresses to physical addresses of the hardware memory and selectively to physical addresses of the system memory by a second memory management unit, such that the operating system of the embedded device is able to access the hardware memory.
