Direct Memory Access(DMA)

The direct memory access (DMA) I/O technique provides direct access to the memory while the microprocessor is temporarily disabled I/O devices are connected to system bus via a special interference circuit known as "DMA Controller" In DMA both CPU and DMA controller have access to main memory via a shared system bus having data address and control lines A DMA controller

Computer System Architecture of Buses

DMA controllers activate the Bus-request line BR before it gain the bus mastership The Signal of Bus- request line is transfer using the logical OR concept from the bus-request line to the other I/O devices When the bus request is activated the processor will activates the bus Grant signal BG1 gives permission to the DMA controller use the bus when it become free The signal is using a

CHAPTER 8

DMA devices make this possible because they can perform I/O transfers independently once these transfers are initiated by the processor Pipelining is a particularly effective way of organizing concurrent activity in a computer system The basic idea is very simple It is frequently encountered in manu-facturing plants where pipelining is commonly known as an assembly-line operation Readers
