This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.

Ajax(asynchronous JavaScript + XML)的定义 基于web标准(standards-based presentation)XHTML+CSS的表示; 使用 DOM(Document Object Model)进行动态显示及交互; 使用 XML 和 XSLT 进行数据交换及相关操作; 使用 XMLHttpRequest 进行异步数据查询、检索; 使用 JavaScript 将所有的东西绑定在一起。英文参见Ajax的提出者Jesse James Garrett的原文。 类似于DHTML或LAMP,AJAX不是指一种单一的技术,而是有机地利用了一系列相关的技术。事实上,一些基于AJAX的“派生/合成”式(derivative/composite)的技术正在出现,如“AFLAX”。 含实例源码。
