How does MMU work in the arm?

The processor MMU works with the cache memory system to control accesses to and from external memory. The MMU also controls the translation of virtual addresses to physical addresses. The MMU controls table-walking hardware that accesses translation tables in main memory.

How will you calculate physical address space in memory management unit?

To compute the physical address:

1. look up the page number in the page table and obtain the frame number.
2. to create the physical address, frame = 17 bits; offset = 12 bits; then 512 = 29. 1m = 220 => 0 – ( 229-1 ) if main memory is 512 k, then the physical address is 29 bits.

What is the role of the memory management unit in translating addresses?

2 Memory management units and address translation. A memory management unit translates addresses between the CPU and physical memory. This translation process is often known as memory mapping because addresses are mapped from a logical space into a physical space.

What is the difference between a virtual address and a physical address in memory management?

Physical addresses refer to hardware addresses of physical memory. Virtual addresses refer to the virtual store viewed by the process. only a portion of the address space that processes do use is loaded into physical memory at a time.

What is page table in memory management?

A page table is the data structure used by a virtual memory system in a computer operating system to store the mapping between virtual addresses and physical addresses. The page table is a key component of virtual address translation which is necessary to access data in memory.

How is data detected in a UART?

How is data detected in a UART? Explanation: The data can be detected by the local clock reference which is generated from the baud rate generator. The baud rate is supplied by the counter or an external timer called baud rate generator which generates a clock signal.
