What is the difference between memory mapped and IO mapped? - TimesMojo
Advertisement I/O is any general-purpose port used by processor/controller to handle peripherals connected to it. I/O mapped I/Os have a separate address space from the memory. … A separate signal is used for addressing an I/O device. Memory-mapped I/Os share the memory space with external memory.

A computer employs RAM chips of 256 x 8 and ROM chips of 1024 x 8. The computer system needs 2K bytes of RAM, 4K bytes of ROM, and four interface units, each with four registers. A memory-mapped I/O configuration is used. The two highest-order bits of the address bus are assigned 00 for RAM, 01 for ROM, and 10 for interface registers.a. How many RAM and ROM chips are needed?b. Draw a memory-address map for the system.c. Give the address range in hexadecimal for RAM, ROM, and interface.Answer for
