Therefore, the multiplication M x 14, where M is the multiplicand and 14 the multiplier may be computed as M x 24 - M x 21. WebThese two methods can achieve this asynchronous way of data transfer: Strobe control: A strobe pulse is supplied by one unit to indicate to the other unit when the transfer has to occur. Handshaking: This method is commonly used to accompany each data item being transferred with a control signal that indicates data in the bus.
