Nvidia's BR02 "High Speed Interconnect" ("HSI") chip was used in their early PCI Express graphics cards, where it acted as a bridge between the PCI Express connection to the computer and the natively AGP GPU. This allowed Nvidia to release a PCI Express graphics card without redesigning the graphics card's GPU for the new interface. It was introduced in 2004. Nvidia has also developed an HSI chip which works in the opposite direction, allowing natively PCI Express GPUs to be used in graphics cards released for the AGP interface.

  • High-Speed Interconnect (oft mit HSI oder HSI-Bridge abgekürzt) ist ein im Jahr 2004 von Nvidia vorgestellter Chip, um Grafikchips mit nativer AGP-Anbindung auch mit einer PCI-Express-Schnittstelle nutzen zu können. Dies hatte vor allem den Grund, dass man bereits bestehende Chipdesigns mit einer neuen Schnittstelle nutzen konnte. Später folgte eine umgekehrte Variante, die es erlaubte die neuen nativen PCI-Express-Mikrochips an AGP anzubinden. Dieses Modell konnte bis zur Geforce-7-Serie eingesetzt werden. Einen ähnlichen Zweck hat ATI Rialto von ATI Technologies. (de)

  • BR02全稱Bridge Revision 02,是NVIDIA公司隨GeForce PCX推出的接橋晶片,其別稱為High Speed Interconnect(HSI),由IBM代工。它可以將AGP訊号轉為PCI-E訊号,亦可將PCI-E訊号轉為AGP訊号。BR02也可与顯示核心一起封裝,以淢低成本,例如NV45/NV48晶片即是NV40晶片與BR02的整合體。 初期NVIDIA使用此晶片,將AGP顯示卡转为PCI-E接口,推出了GeForce PCX系列。但GeForce PCX基於其並不成功的舊產品GeForce FX系列,而且通過其轉換效能更會略微損失,所以接橋晶片備受批評。而當時競爭對手ATi亦挪喻NVIDIA「有路何需搭橋」,皆因其晶片均為原生,即一個晶片同時推出原生PCI-E與原生AGP版本。 在GeForce 6及GeForce 7時期,BR02接橋晶片的優勢終於體現出來,NVIDIA可以方便的將原生支援AGP的顯示卡轉換為PCI-E顯示卡,或將原生支援PCI-E的顯示卡轉換為AGP顯示卡以供老平臺使用。最後迫於成本壓力,ATi亦开發了Rialto單向接橋晶片。 (zh)
