What does bandwidth mean? This problem may be often seen in our daily study or work. I hope you can gain a lot from this question. The following is the reference content that the editor brings to you, let's take a look at it!

There are many areas of bandwidth applications, which can be used to identify the data transmission capacity of signal transmission, the amount of data passing through the link per unit time, and the display ability of the display.

1. In the analog signal system, it is also called bandwidth, which refers to the amount of data that can be transmitted at a fixed time, that is, the ability to transmit data in the transmission pipeline. It is usually expressed as a transmission cycle per second or Hz.

2. In digital equipment, bandwidth refers to the amount of data that can pass through inter-links per unit time. It is usually expressed as bps, that is, the number of bits that can be transmitted per second.

The term bandwidth originally refers to the width of the electromagnetic band, that is, the difference between the highest frequency and the lowest frequency of the signal. At present, it is more widely used in digital communication to describe the maximum rate at which data is theoretically transmitted by a network or line. This is not its academic definition, but is used in an extended way.

Bus bandwidth refers to the total amount of data that the bus can transmit in a unit time, which is equal to the product of the bus bit width and the working frequency. For example, for a 64-bit 800MHz front-end bus, its data transfer rate is equal to 64bit × 800 × 1000 × 1000Hz / 8 (Byte) / 1024 / 1024 / 1024 ≈ 6.0GB/s.

Memory bandwidth refers to the data transmission capacity that the memory bus can provide. For example, if the data transmission frequency of DDR400 memory is 400MHz, then a single module has the bandwidth of 64bit × 400 × 1000 × 1000Hz / 8 (Byte) / 1024 / 1024 / 1024 ≈ 3.0GB/s.
