DMA Data Transfer Modes Explained by nemi rishi is a document available to read on EtoBox.
The document discusses I/O interfaces and direct memory access (DMA). It explains that DMA allows peripherals to directly communicate with memory, removing the CPU from the data transfer process. There are three modes of DMA transfer: burst mode transfers the entire data block at once but keeps the CPU idle longest, cycle stealing mode transfers one byte at a time allowing the CPU to work between transfers, and transparent mode only transfers data when the CPU is not using the buses so it never stops the CP
