In combinational logic is a hazard that depend on the distribution of signal propagation delays in the logic circuits and overall design of a logic circuit function implemented. [1]: 43 Combinational functional hazards In combinational logic are hazards that can be detected and suppressed at a higher level of programming, by studying and ...
Bubbling the pipeline, also termed a pipeline break or pipeline stall, is a method to preclude data, structural, and branch hazards. As instructions are fetched, control logic determines whether a hazard could/will occur. If this is true, then the control logic inserts no operation s (NOP s) into the pipeline. Thus, before the next instruction ...
A race condition or race hazard is the condition of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events, leading to unexpected or inconsistent results.
In digital logic, a don't-care term [1] [2] (abbreviated DC, historically also known as redundancies, [2] irrelevancies, [2] optional entries, [3] [4] invalid combinations, [5] [4] [6] vacuous combinations, [7] [4] forbidden combinations, [8] [2] unused states or logical remainders [9]) for a function is an input-sequence (a series of bits) for which the function output does not matter.
A timing diagram can contain many rows, usually one of them being the clock. It is a tool commonly used in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing diagram can help find and diagnose digital logic hazards.
Huge landslide at La Conchita, 1995. A geologic hazard or geohazard is an adverse geologic condition capable of causing widespread damage or loss of property and life. [1] These hazards are geological and environmental conditions and involve long-term or short-term geological processes.
Fire prevention is a key element of home safety. In 2020, more than 356,500 fires broke out in U.S. homes. These fires caused everything from minor smoke damage to total destruction, including the ...
The Earle latch is hazard free. [21] If the middle NAND gate is omitted, then one gets the polarity hold latch, which is commonly used because it demands less logic. [21] [22] However, it is susceptible to logic hazard. Intentionally skewing the clock signal can avoid the hazard. [22]
