Web23 okt. 2024 · Programmed I/O means I/O that is performed by the CPU directly under program control, as opposed to Direct Memory Access, or DMA, where dedicated hardware is performing the I/O. What’s actually being compared here is polling vs. interrupt control … WebInterrupt-Driven I/O. The primary disadvantage of PIO is that the CPU is totally involved in the slow I/O operation, and spends most of its time remaining idle called busy waiting. The way to get rid of busy waiting is to have the CPU issue an I/O command to an I/O module as usual to start the I/O device, and tell the I/O module to generate an ...
