External memory can be accessed by the [**microprocessor**](https://answers.mindstick.com/qa/97173/what-does-a-microprocessor-mean). Memory mapping is a technique for increasing physical memory access. - The translation between the logical address space and physical memory is known as memory mapping. Memory mapping has three goals: (1) to convert logical to physical addresses, (2) to enhance memory protection , and (3) to improve memory resource management. - Both locally (how long it takes to execute an instruction) and globally, mapping is critical to computer performance (how long it takes to run a set of programs). In effect, the mapping mechanism must translate a logical memory address into a proper physical memory location each time a programme requests that the accompanying memory word be accessed. \ **Read More: [What is the relevance of bus in any microprocessor?](https://answers.mindstick.com/qa/97324/what-is-the-relevance-of-bus-in-any-microprocessor)** --- Original Source: https://answers.mindstick.com/qa/97327/what-is-memory-mapping-with-relation-to-microprocessor Copyright © MindStick Software Pvt.
