órajelalapú

Órajelalapú refers to a characteristic or design principle in digital electronics and computing where operations or functions are synchronized with a clock signal. This clock signal is a periodic waveform, typically a square wave, that provides timing pulses. These pulses dictate when specific actions should occur within a digital circuit.

In a synchronous digital system, all state changes, such as data being written to memory or a flip-flop changing its output, happen in discrete steps aligned with the rising or falling edge of the clock signal. This ensures that different parts of the circuit operate in a coordinated manner, preventing race conditions and simplifying the design process. The frequency of the clock signal, often measured in Hertz (Hz), Gigahertz (GHz), or Megahertz (MHz), determines the maximum speed at which these operations can be performed. A higher clock frequency generally means faster processing.

Asynchronous systems, in contrast, do not rely on a global clock signal. They use handshaking protocols to coordinate operations between different components. However, a vast majority of modern digital devices, including CPUs, microcontrollers, and memory controllers, are built around órajelalapú architectures due to their predictability and ease of design. The term can be applied to various aspects, from the speed of a processor (its clock speed) to the timing of data transfers in a bus system.
