What is the use of cpu multi-threading?

Threads are the basic unit of CPU scheduling and allocation. Multithreading determines how many tasks a single CPU core can handle at the same time without interfering with each other. The multi-threading technology of the CPU can prepare more data to be processed for the computing core, reduce the idle time of the computing core, solve the load balancing problem, make full use of CPU resources, and improve CPU usage.

The Chinese name of CPU is central processing unit. It is a very large-scale integrated circuit and is the computing core and control core of a computer. Today's CPUs use multi-core and multi-thread technology, so what is the use of multi-threading in a CPU?

Threads are the basic unit of CPU scheduling and allocation. Multi-threading determines how many tasks a single core of the CPU can process simultaneously without interfering with each other; allowing multiple threads on the same processor to execute simultaneously and share the processor's execution resources can maximize wide launch and out-of-order over-the-top performance. Volume processing improves the utilization of the processor's computing components and alleviates memory access delays caused by data correlation or cache misses.

CPU's multi-threading technology can prepare more data to be processed for the high-speed computing core and reduce the idle time of the computing core; it solves the load balancing problem, makes full use of CPU resources, and improves CPU usage.

Using multi-threading, several things can be completed at the same time without interfering with each other, which shortens the time required to handle a large number of IO operations or situations.

Benefits of multi-threading:

1. Using threads can put tasks in long-term programs into the background for processing

2. The user interface is more attractive. For example, if the user clicks a button to trigger the processing of an event, a progress bar can pop up to show the progress of the processing.

3. Program The operating efficiency may be improved

4. Threads are more useful in implementing some waiting tasks such as user input, file reading and network sending and receiving data.
