Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

Question

Microprocessor 8086

One of the main difference between
isolated I/O mapping and memory
mapped I/O?
Isolated I/O is faster then memory
O mapped because it is used special
instruction
Skip
The address space dedicated to Isolated
1/0 devices is a part of the memory.
Isolated I/O is slower then memory
mapped because it is used memory
instruction
Isolated I/O can transfer data between the
ports and any register in memory

Answer the following: A section of the memory space with the address from 0x6000 to 0x9FFF needs to be fully partitioned to two peripherals with the same memory size. The first peripheral's address starts at Ox6000 and ends at Ox . The second peripheral's address starts at Ox ends at Ox9FFF. and In embedded programming, let i = 13, then j =i<< 2; we have j = 0x wise operation, let i = 0x00ff and then i &= ~0x0010, we have i = Ox .
