The essential working of AGP

Today, computers have become extremely powerful and dangerous. With just a click of mouse you are dragged and eventually dropped to certain or uncertain locations. Computers offer exciting choices to its users to watch movies, play games or manage documents. Last but not least there is a thrill to connect to the Internet that takes the user to a new world of knowledge and adventure.

Today, the computing aspect has become very advanced from animation discovery to the simpler tasks. Word processing, e-mail sending and graphics designing have certainly developed an intuitive environment of work of the user. The hardware utilized in supporting graphics is called graphics card that connects to a computer to enables graphics. Thus, it is very interesting by the user to explore Accelerated Graphics Port or AGP, which is a dedicated solution to communication enhancing not only the looks but also the speed.

It all began in 1996, when AGP was introduced by Intel. It is the efficient way to deliver the video and 3-D graphics. The standard method then was Peripheral Component Interconnect which is used to deliver multiple information’s from graphic card to CPU. This system was working at highest peaks for several years, but eventually it was found to be lengthier. Internet and many other software programs have become graphic oriented and the need for graphics card excelled in PCI devices.

Although AGP was structured based on PCI bus design, but it uniquely offers point-to-point connection from the graphics card to CPU. With a clear solution for CPU as well as system memory, AGP offers a faster and more efficient solution to avail information for complex graphics.

Enabling AGP graphics

AGP improves the way PCI sends data to CPU. It clears the traffic in data by just increasing the speed of machines that render graphics whilst utilizing system’s resources more effectively in order to reduce the overall drag. There are different options of the dedicated, pipelining and side band addressing methods, which offer the highest capacity of connection. However, with the side band addressing, AGP offers eight additional lines for addressing essentially on data packet. The 3-D graphics are normally formed by texture map, which is loaded from the hard drive to RAM, the system memory till it is utilized. Moreover, if it is sent through PC bus to the graphics card it will be stored in frame buffer, where the graphics card has to be refreshed every time. AGP utilizes more and faster RAM to offer AGP memory. AGB also saves RAM by Graphic Address Remapping Table. Thus, AGP and AGP graphics cards are the essential standards for processing the graphics on PC. Its specification systems are highly Intel and nVidia AGP8x.
