What is the ring counter?

In the computer system, the standard ring counter is the type of counter, which is composed of a shift register, a different type of counter that exists in a sequential logical form. This type of logic is influenced and determined by the previous inputs and the previous history of data. Registers create discrete delays of waveforms or digital signals that are synchronized with certain functions of a discrete and variable amount of phases in the shift register. These phases are called either "D" flip flops or "JK" flip flops. Shift registers once served as a digital memory of the computer and were up to hundreds of phases long.

certain Shift registers can become ring counters if the output data of a particular shift is fed back to its input. When performing this action, this type of register is considered a circular counter, where the final output data of the invertation becomes the initial input date of the flip-flop in the registry. Data in counter -loops continuously, recirculation of data repetition in this closed circuit. This kind of counter withE calls a direct ring or partition.

in a direct ring counter, which consists of 4 bits, the perimeter works according to the binary code, each bit set to 1 or 0, with sets of functions that each bit reset by each flip. In this way, when the first bit is set to 1, all other bits set to 0. With each successive flip flop, the next bit that follows is set to 1, while the bit that was previously set to 1 is set to 0. The movement that this counter exposes is called "rotary" because of its circular nature.

Another type of counter is called the counter -twisted circle, also known as Johnson Ring Counter or Moebius Counter. Feedback data of this type of add -on is similar to the Overbek counter except that the final output data of the overrun isturned and brought back to the initial inlet of the flip. This counter is beneficial because it requires half the amount of flip flops that may require a counter. In some cases, this type of counter may even work twice as fast, reducing the operation time. The twisted ring is available as standard TTL or IC CMOS forms.
