Asynchronous circuits and theory surrounding is a part of several steps in integrated circuit design, a field of digital electronics engineering. Asynchronous circuits are contrasted with synchronous circuits, in which changes to the signal values in the circuit are triggered by repetitive pulses called a clock signal. Most digital devices ...
In digital computing, the Muller C-element (C-gate, hysteresis flip-flop, coincident flip-flop, or two-hand safety circuit) is a small binary logic circuit widely used in design of asynchronous circuits and systems. It outputs 0 when all inputs are 0, it outputs 1 when all inputs are 1, and it retains its output state otherwise.
In metastable states, the circuit may be unable to settle into a stable '0' or '1' logic level within the time required for proper circuit operation. As a result, the circuit can act in unpredictable ways, and may lead to a system failure, sometimes referred to as a "glitch". [2] Metastability is an instance of the Buridan's ass paradox.
Parts of the system communicate using the early four-phase asynchronous protocol. The construction of DIMS logic gates comprises generating every possible minterm using a row of C-elements and then gathering the outputs of these using OR gates which generate the true and false output signals. With two dual-rail inputs the gate would be composed ...
Asynchrony (game theory), when players in games update their strategies at different time intervals; Asynchronous learning, an educational method in which the teacher and student are separated in time; Asynchronous motor, a type of electric motor; Asynchronous multiplayer, a form of multiplayer gameplay in video games
A quasi-delay-insensitive circuit (QDI circuit) is an asynchronous circuit design methodology employed in digital logic design.Developed in response to the performance challenges of building sub-micron, multi-core architectures with conventional synchronous designs, QDI circuits exhibit lower power consumption, extremely fine-grain pipelining, high circuit robustness against process–voltage ...
A delay-insensitive circuit is a type of asynchronous circuit which performs a digital logic operation often within a computing processor chip. Instead of using clock signals or other global control signals , the sequencing of computation in delay-insensitive circuit is determined by the data flow.
Deterministic asynchronous updated Boolean networks (DRBNs) are not synchronously updated but a deterministic solution still exists. A node i will be updated when t ≡ Q i (mod P i) where t is the time step. [26] The most general case is full stochastic updating (GARBN, general asynchronous random Boolean networks). Here, one (or more) node(s ...
