  2. Intel 4004 - Wikipedia

    en.wikipedia.org/wiki/Intel_4004

    Instruction execution time 1 or 2 machine cycles (10.8 or 21.6 μs), 46 250 to 92 500 instructions per second. Adding two 8-digit decimal numbers (32 bits each, assuming 4-bit BCD digits) takes a claimed 850 μs, or approximately 79 machine cycles (632 clock ticks), for an average of just under 10 cycles (80 ticks) per digit pair and an ...

  3. Delay slot - Wikipedia

    en.wikipedia.org/wiki/Delay_slot

    In computer architecture, a delay slot is an instruction slot being executed without the effects of a preceding instruction. [1] The most common form is a single arbitrary instruction located immediately after a branch instruction on a RISC or DSP architecture; this instruction will execute even if the preceding branch is taken.

  4. Digital timing diagram - Wikipedia

    en.wikipedia.org/wiki/Digital_timing_diagram

    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 .

  5. Delay calculation - Wikipedia

    en.wikipedia.org/wiki/Delay_calculation

    Elmore delay [5] is a simple approximation, often used where speed of calculation is important but the delay through the wire itself cannot be ignored. It uses the R and C values of the wire segments in a simple calculation. The delay of each wire segment is the R of that segment times the downstream C. Then all delays are summed from the root.

  6. Delay-line oscillator - Wikipedia

    en.wikipedia.org/wiki/Delay-line_oscillator

    A delay-line oscillator is a form of electronic oscillator that uses a delay line as its principal timing element. The circuit is set to oscillate by inverting the output of the delay line and feeding that signal back to the input of the delay line with appropriate amplification. The simplest style of delay-line oscillator, when properly ...

    The 4004 was designed for Busicom, which had earlier proposed a multi-chip design in 1969, before Faggin's team at Intel changed it into a new single-chip design. The 4-bit Intel 4004 was soon followed by the 8-bit Intel 8008 in 1972.

  9. Analog delay line - Wikipedia

    en.wikipedia.org/wiki/Analog_delay_line

    A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed ...
