What do GPU VPU mean?

1. GPU: Graphics processor, also known as display core, visual processor, and display chip, is a microprocessor that specializes in image computing on personal computers, workstations, game consoles, and some mobile devices.

2. VPU has two meanings: 1. The part of the processor used to arrange data.

2. (Video processing unit) A concept proposed by ATI to distinguish it from traditional GPU (graphics processing chip).

The main function is video processing capabilities and optimizing the image of the TV.

Extended information: The purpose of GPU is to convert and drive the display information required by the computer system, and to provide line scan signals to the display to control the correct display of the display. It is an important component connecting the display and the personal computer motherboard, and is also the key to "human-computer dialogue"

One of the important equipment.

Simply put, GPU is a display chip that can support T&L (polygon conversion and light source processing) from the hardware. Since T&L is an important part of 3D rendering, its role is to calculate the 3D position of polygons and process dynamic light effects. It can also be called

"Geometry processing".

Most of today's GPUs have 2D or 3D graphics acceleration capabilities.

If the CPU wants to draw a two-dimensional graphic, it only needs to send an instruction to the GPU.

For example, "Draw a rectangle with a length and width of a×b at the coordinate position (x, y)", the GPU can quickly calculate all the pixels of the graphic, and draw the corresponding graphic at the specified position on the display.

After finishing, it notifies the CPU "I have finished drawing", and then waits for the CPU to issue the next graphics instruction.
