设计应用了最先进的ARM嵌入式技术,利用ARM丰富的内部设备,实现了光谱数据的传输和基于触摸屏的人机交互平台。实现近红外光谱仪器操作简单化,体现了ARM微处理器的优胜之处。   1. 引言   近红外光谱主要是由分子振动的非谐振性使分子振动从基态向高能级跃迁时产生的,记录的主要是含氢基团C-H、O-H、N-H等振动的倍频和合频吸收[1],具有丰富的物质结构和组成信息,非常适合用于碳氢有机物质的组成性质测量。近红外光谱作为迅速崛起的光谱分析技术在分析测试领域中起的作用越来越引起人们关注,由于样品在分析时基本不需要处理,且不破坏和消耗样品,自身又无环境污染,近红外光谱分析技术堪称是绿色分析仪器

Repair techniques for nanoscale memories are becoming more important to cope with ever-increasing “errors” causing degraded yield and reliability. In fact, without repair techniques, even modern CMOS LSIs, such as MPUs/SoCs, in which memories have dominated the area and performances, could not have been successfully designed. Indeed, various kinds of errors have been prominent with larger capacity, smaller feature size, and lower voltage operations of such LSIs. The errors are categorized as hard/soft errors, timing/voltage margin errors, and speed-relevant errors. Hard/soft errors and timing/voltage margin errors, which occur in a chip, are prominent in a memory array because the array comprises memory cells having the smallest size and largest circuit count in the chip. In particular, coping with the margin errors is vital for low-voltage nanoscale LSIs, since the errors rapidly increase with device and voltage scaling. Increase in operating voltage is one of the best ways to tackle the issue. However, this approach is unacceptable due to intolerably increased power dissipation, calling for other solutions by means of devices and circuits. Speed-relevant errors, which are prominent at a lower voltage operation, comprise speed-degradation errors of the chip itself and intolerably wide chip-to-chip speed-variation errors caused by the ever-larger interdie designparameter variation. They must also be solved with innovative devices and circuits. For the LSI industry, in order to flourish and proliferate, the problems must be solved based on in-depth investigation of the errors.
