再过几个月,联合微电子公司(UMC)将提供一组支撑电路,使i486和386处理器的运行速度提高到50MHz。 UMC的82C480由一个集成存储控制器(起重要作用的Cache控制器、系统控制器、外部控制器以及一些逻辑元件组成。它使用1倍CPU时钟设计,因而具有i4861倍时钟输入的优点。但也可以在i486用Intel实现的1倍时钟设计,而在486机器上的典型芯片组可使用2倍 In a few months, United Microelectronics Corp. (UMC) will provide a set of support circuits that will increase the i486 and 386 processors to 50MHz. The UMC’s 82C480 consists of an integrated memory controller, the most important Cache controller, system controller, external controller, and some logic components. It uses a 1x CPU clock design and therefore has the advantage of an i4861x clock input. A 1x clock design with Intel in i486, and 2x the typical chipset on a 486 machine
