Windows device driver information for ATI-AMD-762 AGP Host to PCI Bridge

ATI-AMD-762 AGP Host to PCI Bridge features an Accelerated Graphics Ports (AGP) driver. The AGP interface has several advantages over the PCI interface. The advantage that AGP has over PCI is that it gives a dedicated pathway from the slot to the processor instead of having to share PCI bus. This point-to-point connection has enabled AGP to clock a faster speed than PCI. Sideband addressing is used in AG. It means that the address buses are separated from the data buses therefore no reading will be required in order to get the addressing information. The additional 8- bit bus enables the graphics controller to give new requests as well as commands simultaneously while other data for AGP flows through the main 32 address lines. Thus compared to PCI cards, the ATI-AMD-762 AGP Host to PCI Bridge has increased data throughput.

The AGP driver gives support for the AGP interface that is independent of machines. AGP ports are found on several PCI systems as well as PC-based systems. How it functions is that the AGP chipset is placed between the graphics accelerator and the PCI to host bridge. This product is able to give a dedicated graphics specification which provides excellent performance and which is capable of moving huge columes of data from the memory host and transmit it to the graphics accelerator directly. At the moment, the AGP specification supports 528 MB/s maximum bandwidth. It uses GART (Graphics Address Remapping Table) to give a scattered pages view in the host memory that is physically contiguous. It functions well for the AMD-762 System controller. For the ATI-AMD-762 AGP Host to PCI Bridge product to function effectively and efficiently, users are advised to always ensure that they are using the latest version of the device driver. Old versions are known to create conflict and can produce errors in the work of the device. It is highly recommended you run a free registry scan for and ATI-AMD-762 AGP Host to PCI Bridge errors before installing any driver updates.
