There's just no way of validating that your software will run the way you expect on every vari ation of every system in the world. Software has become too complex, and validating every possible system permutation, input combination, and software feature is nearly impossible. For example, if you are developing the next Flash video game, are you sure your code will run in every browser, with any recent version of Flash, on all platforms, all while making sure that your game still performs adequately? Most people can't get this kind of coverage cost effectively.

Processor completes the current bus cycle and then asserts the bus grant signal to the device. The device then asserts the bus grant ack signal. The processor senses in the change in the state of bus grant ack signal and starts listening to the data and address bus for DMA activity. The DMA device performs the transfer from the source to destination address. During these transfers, the processor monitors the addresses on the bus and checks if any location modified during DMA operations is cached in the processor. If the processor detects a cached address on the bus, it can take one of the two actions: Processor invalidates the internal cache entry for the address involved in DMA write ope...
