  2. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    The C language provides the four basic arithmetic type specifiers char, int, float and double (as well as the boolean type bool), and the modifiers signed, unsigned, short, and long.

  3. Boolean circuit - Wikipedia

    en.wikipedia.org/wiki/Boolean_circuit

    For example, the size complexity of a Boolean circuit is the number of gates in the circuit. There is a natural connection between circuit size complexity and time complexity . [ 2 ] : 355 Intuitively, a language with small time complexity (that is, requires relatively few sequential operations on a Turing machine ), also has a small circuit ...

  4. C-element - Wikipedia

    en.wikipedia.org/wiki/C-element

    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.

  5. Logic gate - Wikipedia

    en.wikipedia.org/wiki/Logic_gate

    A logic circuit diagram for a 4-bit carry lookahead binary adder design using only the AND, OR, and XOR logic gates.. A logic gate is a device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output.

  6. Gate array - Wikipedia

    en.wikipedia.org/wiki/Gate_array

    A gate array is an approach to the design and manufacture of application-specific integrated circuits (ASICs) using a prefabricated chip with components that are later interconnected into logic devices (e.g. NAND gates, flip-flops, etc.) according to custom order by adding metal interconnect layers in the factory. It was popular during the ...

  7. Hardware description language - Wikipedia

    en.wikipedia.org/wiki/Hardware_description_language

    In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, usually to design application-specific integrated circuits (ASICs) and to program field-programmable gate arrays (FPGAs).

  8. Emitter-coupled logic - Wikipedia

    en.wikipedia.org/wiki/Emitter-coupled_logic

    The picture represents a typical ECL circuit diagram based on Motorola's MECL. In this schematic, transistor T5′ represents the output transistor of a previous ECL gate that provides a logic signal to input transistor T1 of an OR/NOR gate whose other input is at T2 and has outputs Y and Y.

  9. UML state machine - Wikipedia

    en.wikipedia.org/wiki/UML_state_machine

    The state diagram from Figure 2 is an example of an extended state machine, in which the complete condition of the system (called the extended state) is the combination of a qualitative aspect—the state variable—and the quantitative aspects—the extended state variables.
