The systemic PC tire AGP
The systemic PC tire AGP The AGP standard was developed by the company Intel in order to quicken the input and output of data onto the video adapter without actually changing the existing PCI tire standard an to increase the PC productivity, when dealing with three-dimensional graphic applications. In 1997 the first version of the AGP 1.0 tire was developed. The structure of the AGP tire presents a separate slot with the supply of 3.3 V, similar to the PCI slot, but not compatible with it. The PCI video adapter may not be installed into the slot and vice versa. The new tire has advantages like as the speed of data transmission up to 532 Mb/s, the possibility to cancel the multiplexing tire address and data mechanism (on PCI physical lines first acquire the address, then the data). To increase the throughput capacity of the AGP tire the standard is capable of transmitting data by means of special additional signals, used as strobes, instead of the CLK signal within the common regimen (regimens "2x" and "4х"). In the regimen "2x" the throughput capacity is 532M/s. In the regimen "4х" the throughput capacity increases to 1064 M/s. Besides the traditional address method as in the PCI - when the address isgiven first and then the tires acquire data, in the AGP the so-called "sideway line addressing" is used, when the tires of the address and data are separated and may be transmitted simultaneously. The speed of exchange in this regimen is significantly higher, as the time spent on transmitting the address along the tire is eliminated. The data processing on the AGP takes place according to an algorithm, different from that of the PCI. On the PCI data appears on the address after some time. On the AGP the address batch is released first and then comes the data batch. The basic processing of the three-dimensional images is performed in the basic memory of the computer both by the central processor and that of the video adapter. In December 1997 the company Intel released the preliminary version of the standard AGP 2.0, and in May 1998 the final version was released. The transmission speed may be increased twice compared to the version 1.0 - the regimen is also called "4x". In July 1998 the company Intel released the specification version for the AGP Pro, significantly differing structurally from the AGP 2.0. In November 2000 the company Intel released the preliminary version of the ...
