A memory mapped register is a register that has its specific address stored in a known memory location.

∙ 17y agoRegisters are small units of memory that live on the CPU. They hold small units of data, like source and destination characters for a string move, or address pointers. They aren't normally anyone thinks about but the few living assembly language programmers and complier designers.

What are the types of memory register?
what is register
What is a difference between register and a memory location?
difference between register and memory location
Cache memory and register memory?
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
Advantage of using a CPU register over memory locations?
CPU register is faster than memory loacations
Memory address register is used to store?
memory addres register is used hold data addresses that refer to the data portion of the memory(by umar farooq.pk) memory addres register is used hold data addresses that refer to the data portion of the memory(by umar farooq.pk)
How does fetch decode cycle work?
The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.
How does the Fetch Decode Execute work?

The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.

Why register to register instruction is faster?
Register to register addressing mode is faster because you don't have to do an extra memory access cycle or more.Register to register addressing mode is faster because:Registers are part of and are directly accessibility by the CPU assembly.They electronics that make up a register use more expensive but faster circuitry.Since it does not require memory access, the steps and time involved in memory address decoding and memory access are skipped.
What do you mean by MAR and MBR in computer organization?
MAR-memory address register used stored the address of the memory loaction MBR- memory buffer register is the actully data.
