Data transfer modes in computer architecture
WebFeb 4, 2024 · There are basically three modes of data transfer, which are given below: Programmed I/O Interrupt-initiated I/O Direct memory access (DMA) 1. Programmed I/O: Programmed Input/output (PIO) mode is a type of data transfer mode in which the CPU controls the transfer of data between a device and main memory. Weba) Burst Mode: In this mode DMA handover the buses to CPU only after completion of whole data transfer.Meanwhile, if the CPU requires the bus it has to stay ideal and wait for data transfer. b) Cycle Stealing Mode: In …
