AGP：加速图形端口 (AGP: Accelerated Graphics Port )
AGP is an abbreviation of the "Accelerated Graphics Port".
AGP是“加速图形端口”的缩写 。
It was created and developed as a high-speed point-to-point channel for putting together a video card to a system of the computer, first and foremost to help out and support the acceleration of 3D computer graphics. It was at the beginning created and developed as a descendant to PCI-type connections for video cards. As of 2004, AGP has been gradually carried out in regular stages in support of PCI Express; by mid-2008, PCI Express cards have taken over the market and simply a small number of AGP models were obtainable and accessible, with GPU manufacturers and add-in board partners in due course reducing support for the interface in support of PCI Express.
它是作为高速点对点通道而创建和开发的，用于将视频卡放到计算机系统中，首先是帮助并支持3D计算机图形的加速。 它最初是作为视频卡的PCI类型连接的后代而创建和开发的。 从2004年开始， AGP已逐步定期进行，以支持PCI Express。 到2008年年中，PCI Express卡已经占领了市场，只有少量AGP型号可供使用，GPU制造商和附加板合作伙伴会适时减少对接口的支持，以支持PCI Express。
AGP历史 (AGP History)
The AGP slot first came out and emerged on x86-compatible system boards based on Socket 7 Intel P5 Pentium and Slot 1 P6 Pentium II processors.
AGP插槽首次出现并出现在基于Socket 7 Intel P5 Pentium和Slot 1 P6 Pentium II处理器的x86兼容系统板上。
On August 26, 1997, Intel launched AGP support with the i440LX Slot 1 chipset, and an overflow of products followed from the entire most significant system board sellers.
1997年8月26日，英特尔推出了i440LX Slot 1芯片组对AGP的支持，随后，整个最重要的系统板销售商也纷纷涌入产品。
AGP版本 (AGP Versions)
In 1997, Intel launched "AGP specification 1.0".
1997年，英特尔推出了“ AGP规范1.0”。
It mentioned 3.3 V signals and 1× and 2× speeds.
它提到了3.3 V信号以及1倍和2倍速度。
Specification 2.0 documented 1.5 V signaling, which could be used at 1×, 2× and the further 4× speed and 3.0 supplemented 0.8 V signaling, which could be controlled and managed at 4× and 8× speeds.
规范2.0记录了1.5 V信号，可以以1倍，2倍以及进一步的4倍速度使用，而3.0补充了0.8 V信号，可以以4倍和8倍的速度进行控制和管理。
Existing versions are listed below in the given following table.

官方扩展 (Official Extensions)
AGP Pro
AGP专业版
An official extension for cards that needed more electrical power, with an extended slot with supplemented pins for that purpose.
这是需要更多电力的卡的官方扩展，带有用于此目的的扩展插槽和补充的插针。
AGP Pro cards were generally workstation-class cards used to accelerate professional computer-aided design applications made use of in the fields of architecture, machining, engineering, simulations, and related fields.
AGP Pro卡通常是工作站级卡，用于加速在建筑，机械加工，工程，模拟和相关领域中使用的专业计算机辅助设计应用程序。
64-bit AGP
64位AGP
A 64-bit channel was formerly projected as an elective standard for AGP 3.0 in draft documents, other than it was dropped in the last version of the standard.
以前在文档草稿中计划将64位通道作为AGP 3.0的可选标准，但该标准的最新版本中已删除了该通道。
The standard enables 64-bit transfer for AGP8× reads, writes, and fast writes; 32-bit transfer for PCI operations.
该标准支持AGP8×读取，写入和快速写入的64位传输。 PCI操作的32位传输。
