Sequential logic — In digital circuit theory, sequential logic is a type of logic circuit whose output depends not only on the present input but also on the history of the input. This is in contrast to combinational logic, whose output is a function of, and only of … Wikipedia
Logic optimization — a part of logic synthesis, is the process of finding an equivalent representation of the specified logic circuit under one or more specified constraints. Generally the circuit is constrained to minimum chip area meeting a prespecified delay.… … Wikipedia
Logic gate — A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output. Depending on the context, the term may refer to an ideal… … Wikipedia
Logic design — In electronic design, logic design is a step in the standard design cycle in which the functional design of an electronic circuit is converted into the representation which captures logic operations, arithmetic operations, control flow, etc. A… … Wikipedia
Logic programming — is, in its broadest sense, the use of mathematical logic for computer programming. In this view of logic programming, which can be traced at least as far back as John McCarthy s [1958] advice taker proposal, logic is used as a purely declarative… … Wikipedia
Logic synthesis — is a process by which an abstract form of desired circuit behavior (typically register transfer level (RTL) or behavioral) is turned into a design implementation in terms of logic gates. Common examples of this process include synthesis of HDLs,… … Wikipedia
Sequential function chart — (SFC) is a graphical programming language used for PLCs. It is one of the five languages defined by IEC 61131 3 standard. The SFC standard is defined in IEC 848, Preparation of function charts for control systems , and was based on GRAFCET.It can … Wikipedia
Sequential manual transmission — A sequential manual transmission (or sequential manual gearbox) is a type of manual transmission used on motorcycles and high performance cars or auto racing, where gears are selected in order, and direct access to specific gears is not… … Wikipedia
Combinational logic — Not to be confused with combinatory logic, a topic in mathematical logic. In digital circuit theory, combinational logic (sometimes also referred to as combinatorial logic) is a type of digital logic which is implemented by boolean circuits,… … Wikipedia
Programmable logic device — A programmable logic device or PLD is an electronic component used to build reconfigurable digital circuits. Unlike a logic gate, which has a fixed function, a PLD has an undefined function at the time of manufacture. Before the PLD can be used… … Wikipedia
