The 8237 dma controller

Web8237 DMA Controller. Introduction Drect Memory Access (DMA) allows devices to transfer data without subjecting the processor a heavy overhead. Otherwise, the processor would have to copy each piece of data from the source to the destination. This is typically slower than copying normal blocks of memory since access to I/O devices over a peripheral bus … WebThe block of 8237 that decodes the various commands given to the 8237 by the CPU is. a) timing and control block. b) program command control block. c) priority block. d) none of the mentioned.

WebDMA controller commonly used with 8088 is the 8237 programmable device. The 8237 is in fact a special-purpose microprocessor. Normally it appears as part of the system controller chip-sets. The 8237 is a 4-channel device. Each channel is dedicated to a specific peripheral device and capable of addressing 64 K bytes section of memory. WebThe DMAC acquires control of the system bus. The DMAC sends the DACK signal to the I/O peripheral and the DMA transfer begins. After every byte is transferred, the address register is incremented (or decremented) and the count register is decremented. This continues till the count reaches zero (Terminal count). Now the DMA transfer is completed. http://dylucknow.weebly.com/uploads/6/7/3/1/6731187/8237_dma_controller.pdf fedex west st paul hours
