随着多媒体应用的不断深入,高色彩、高分辩的图形处理,以及3D着色所需的大量纹理缓冲内存,使得现在的PCI显卡不堪重负。于是AGP显卡应运而生,它克服了PCI显卡设备的种种缺陷。简单地说,AGP是继ISA总线、EISA总线、VESA总线、PCI总线之后,在PC机上出现的一个新的总线形式,只不过它不像以前的总线类型那样,由一组设备共享带宽,而是作为一个专门用于图形处理的通道。正因为它只支持一个AGP设备,所以它现在还不可能取代PCI,只能与PCI共存。 With the deepening of multimedia applications, high-color, high-resolution graphics, as well as a large number of 3D rendering color texture buffer memory, making the current PCI video card overwhelmed. So AGP graphics came into being, it overcomes the various defects of the PCI graphics device. In short, AGP is a new form of bus that appears on a PC after an ISA bus, an EISA bus, a VESA bus, and a PCI bus, except that it does not share bandwidth by a group of devices unlike the previous bus types, Is used as a dedicated channel for graphics processing. Just because it only supports one AGP device, it is not possible to replace PCI now and only co-exist with PCI.
