Asynchronous timing means that between two devices there is no deterministic timing relationship. It means the NI hardware does not actively adjust the timing of signals to align them with a specific clock edge.
Synchronous timing refers to events that occur simultaneously or in a set order, while asynchronous timing refers to events that occur at different times or independently. In computing, synchronous timing means actions are performed in a fixed order and generally halt until completion, while asynchronous timing allows tasks to be executed in parallel without waiting for each other to finish.
Asynchronous
asynchronous bus A bus that interconnects devices of a computer system where information transfers between devices are self-timed rather than controlled by a synchronizing clock signal.
1. Syncrhonous bus includes clock in control lines whereas asynchronous bus is not clocked. 2. the devices which need to be connected by synchronous bus should be at same speed whereas an asynchronous bus may connect many devices with varying speeds. 3. A fixed protocol is defined to communicate using synchronous bus which is relative to the clock. An asynchronous bus uses handshaking protocol.
With timing, sent from end to end. Examples are synchronous data with explicit timing circuits at interfaces and plesiochronous where the timing is embedded in the main signal by line codes. Asynchronous, without timing is historical and relates to teleprinter speeds up to 300 bit/s.
A Synchronous Sequential Circuit is a system whose behavior can be defined on the timing of their signals , where in the case of asynchronous sequential circuit depend upon the order in which its inputs signals change and can be affected at any instance of time . (reference : M. Moris Mano)
The bits associated with synchronization and framing increase the processing overhead in asynchronous time division multiplexing. These bits are necessary for maintaining the timing and alignment of data streams from multiple sources within the system.
Synchronous flip-flops change outputs synchronously to a clock signal, while asynchronous flip-flops can change outputs regardless of the clock signal. Asynchronous flip-flops are not as commonly used due to potential timing hazards, while synchronous flip-flops are widely used in digital circuits to ensure reliable operation.
