WebInterrupt-based input/output guarantees the same rate, as long as the processor is not overloaded. DMA-based input/output is a block-based version of interrupt-based … WebThis indicates that the Input Output Transfer Techniques is initiated by the external I/O device. When interrupted, the microprocessor stops the execution of the program and transfers the program control to an interrupt service routine. This interrupt service routine performs the data transfer. chuck shoes converse

Conversely, when the output is set to high, it is actively "pushed" toward Vcc. Simplified, it looks like this: An Open-Drain output, on the other hand, is only active in one direction. It can pull the pin towards ground, but it cannot drive it high.

WebInterrupt-driven I/O Device controller does most of the work, notifies CPU when done. CPU still has to extract data itself. DMA-based I/O DMA controller takes over CPU's role, interrupts CPU when data is available in memory. Advantage: minimum load on CPU, especially in the form of fewer interrupts since DMA controller can do more buffering.
