is also an independent system, so it is called a video subsystem. Due to hardware design, the CPU can access the video memory of the video subsystem through the bus, but the display coprocessor cannot access the system memory on the motherboard. However, the speed of the bus is far from enough. When the CPU and display coprocessor perform a large amount of data throughput, the bus becomes abnormal and congested. To solve this problem, the AGP structu
