Clock Cycle (also known as clock period, clock tick, or simply a tick or a cycle) is the minimum time unit required to perform all the most basic operations in a synchronous circuit such as a value transfer between two buffers. The length of a single clock cycle is the time required for one complete clock pulse. It is the reciprocal of the clock speed.
Overview
The clock cycle is a fundamental part of all synchronous circuits which must accommodate the time taken for the longest critical path for all possible states in a circuit. In other words, it's usually the sum of all the wire and switching delay for the longest indivisible portion of the circuit. The clock cycle is usually a constant value, although various power management mechanisms can modulate it to achieve better performance and efficiency attributes.
