AGP：加速圖形端口 (AGP: Accelerated Graphics Port )

AGP is an abbreviation of the "Accelerated Graphics Port".

AGP是“加速圖形端口”的縮寫 。

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.

它是作為高速點(diǎn)對(duì)點(diǎn)通道而創(chuàng)建和開發(fā)的，用于將視頻卡放到計(jì)算機(jī)系統(tǒng)中，首先是幫助并支持3D計(jì)算機(jī)圖形的加速。 它最初是作為視頻卡的PCI類型連接的后代而創(chuàng)建和開發(fā)的。 從2004年開始， AGP已逐步定期進(jìn)行，以支持PCI Express。 到2008年年中，PCI Express卡已經(jīng)占領(lǐng)了市場(chǎng)，只有少量AGP型號(hào)可供使用，GPU制造商和附加板合作伙伴會(huì)適時(shí)減少對(duì)接口的支持，以支持PCI Express。

AGP歷史 (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插槽首次出現(xiàn)并出現(xiàn)在基于Socket 7 Intel P5 Pentium和Slot 1 P6 Pentium II處理器的x86兼容系統(tǒng)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，英特爾推出了i440LX Slot 1芯片組對(duì)AGP的支持，隨后，整個(gè)最重要的系統(tǒng)板銷售商也紛紛涌入產(chǎn)品。

AGP版本 (AGP Versions)

• In 1997, Intel launched "AGP specification 1.0".

  1997年，英特爾推出了“ AGP規(guī)范1.0”。

• It mentioned 3.3 V signals and 1× and 2× speeds.

  它提到了3.3 V信號(hào)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.

  規(guī)范2.0記錄了1.5 V信號(hào)，可以以1倍，2倍以及進(jìn)一步的4倍速度使用，而3.0補(bǔ)充了0.8 V信號(hào)，可以以4倍和8倍的速度進(jìn)行控制和管理。

官方擴(kuò)展 (Official Extensions)

AGP Pro

AGP專業(yè)版

• An official extension for cards that needed more electrical power, with an extended slot with supplemented pins for that purpose.

  這是需要更多電力的卡的官方擴(kuò)展，帶有用于此目的的擴(kuò)展插槽和補(bǔ)充的插針。

• 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卡通常是工作站級(jí)卡，用于加速在建筑，機(jī)械加工，工程，模擬和相關(guān)領(lǐng)域中使用的專業(yè)計(jì)算機(jī)輔助設(shè)計(jì)應(yīng)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.

  以前在文檔草稿中計(jì)劃將64位通道作為AGP 3.0的可選標(biāo)準(zhǔn)，但該標(biāo)準(zhǔn)的最新版本中已刪除了該通道。

• The standard enables 64-bit transfer for AGP8× reads, writes, and fast writes; 32-bit transfer for PCI operations.

  該標(biāo)準(zhǔn)支持AGP8×讀取，寫入和快速寫入的64位傳輸。 PCI操作的32位傳輸。
