Buses are categorized based on their role, such as system buses (also known as internal buses, internal data buses, or memory buses) connecting the CPU and memory. Expansion buses, also called peripheral buses, extend the system to connect additional devices, including peripherals.

后端总线 （Back Side Bus，BSB）： 也叫本地总线（Local Bus）或片内总线（On-chip Bus），是 CPU 芯片内部独立使用的总线。CPU 芯片内部一个或多个核心、Cache 之间的通信将不需要占用芯片外的系统总线。

2024年6月13日 · A computer bus is a communication system within a computer or between computers that transfers data between different components. The purpose of buses is to reduce the number of "pathways" needed forcommunication between the components, by carrying out all communications over a single data channel.

2024年10月1日 · 由于 CPU 需要发送控制信息、数据信息、地址信息，这就会导致CPU的引脚数目过多，CPU体积增大，为了解决这个问题，提出了 引脚复用，即CPU的同一根引脚可以用于 分时传输不同类型信息。 但是这也引入了一个新问题，即 实际应用过程中，不同类型的信息要使用其对应的专用通道进行传输，比如，地址信息要使用专用的地址总线通道进行传输. 对应的解决方案就是在CPU外部设计一部分电路，将CPU的复用引脚都接入到这部分电路上， 通过这部分 …

2020年5月11日 · 控制总线（Control Bus，CB）用于在CPU（或DMA控制器）与存储器、I/O接口之间传输控制和状态信息。 从微机体系结构来看，有两种总线结构，即单总线结构和多总线结构。

2019年6月27日 · 系统总线 (System Bus)，又称内总线。 用于计算机各组成部分 (CPU、内存、I\O接口等)之间的信息传输。 CPU通过系统总线对存储器的内容进行读写，同样经过系统总线，实现将CPU内数据写入外设，或由外设读入CPU。 元件级总线。 用于一块电路板内各元器件的连接。 通信总线，又称外总线。 用于计算机与外设或计算机与计算机之间的连接或通信。 传输各功能部件之间的数据信息。 其位数称为数据总线宽度，与机器字长、存储字长有关，一般为 8 位 …

The CPU bus is a fundamental component of computer architecture, serving as the communication medium between the CPU, memory, and other systems. By exploring its types, functions, architectural considerations, and impacts, we’ve unveiled its vital role in the efficient operation of computers.

A computer bus is a communication pathway that allows various components within a computer system to transfer data and signals between each other. It serves as a wired physical connection or set of wires running across connecting various system components.

2025年1月26日 · In simple terms, a bus can be defined as a group of wires or connections that carry signals between components in a compute system. The CPU orchestrates numerous tasks, including arithmetic calculations, logical operations, and accessing memory.

2025年2月1日 · A bus in a computer's CPU (Central Processing Unit) is a communication system that transfers data between components, enabling seamless interaction among the CPU, memory, and input/output devices. There are different types of buses, including data buses, address buses, and control buses, each serving a vital role in ensuring efficient ...
