Address mapping SlideShare. Memory-mapped I/O uses the same address space to address both memory and I/O devices. The memory and registers of the I/O devices are mapped to (associated with) address values. So when an address is accessed by the CPU, it may refer to a portion of physical RAM, or it can instead refer to memory of the I/O device. Thus, the CPU instructions, Fast memory technology is more expensive per bit than slower memory Solution: organize memory system into a hierarchy Entire addressable memory space available in largest, slowest memory Incrementally smaller and faster memories, each containing a subset of the memory below it, proceed in steps up toward the processor.

memory is done by means of MAR (memory address register). If the memory has 2n locations then the address field must be on n bits. Because the modern memory modules are getting larger with each day, it results that the number of ranks used for address is steadily increasing also, therefore the instructions whose operands are in execution of instruction. This register is also a memory pointer. Memory location have 16-bit address. It is used to store the execution address. The function of the program counter is to Each instruction is represented by a sequence of bits within the computer. The instruction is CPU Architecture

Each byte is assigned a memory address whether or not it is being used to store data. The computer s CPU uses the address bus to communicate which memory address it wants to access, and the memory controller reads the address and then puts the data stored in that memory address back onto the address bus for the CPU to use.
