Direct memory access in embedded systems

In the original IBM PC (and the follow-up PC/XT), there was only one Intel 8237 DMA controller capable of providing four DMA channels (numbered 0–3). These DMA channels performed 8-bit transfers (as the 8237 was an 8-bit device, ideally matched to the PC's i8088 CPU/bus architecture), could only address the first (i8086/8088-standard) megabyte of RAM, and were limited to addressing single 64 kB segments within that space (although the source and destinati… WebDirect memory access, DMA, Embedded systems,Interview Tips,Online interview tips,Government jobs March 2024, IT Company jobs, MNC jobs, Apple Recruitment, I...
