, Learning Objectives
1
1. To understand the architecture and role of an Input-
Output Processor in handling I/O operations
independently from the CPU.
2. To learn how the IOP manages I/O device control, data
transfer, and communication with peripheral devices
using its own instruction set.
3. To analyze how IOPs enhance system efficiency and
performance by offloading I/O processing tasks from the
main processor.
