在深亚微米技术中，与全局片上互连相关的串扰延迟变得更加严重，因此可以极大地影响整个系统的性能。基于Sotiriadis提出的延迟模型，可以根据延迟对总线上的转换模式进行分类。使用这种分类，串扰避免码（CAC）已被提出来减轻串扰延迟，通过限制在总线上的过渡模式。在本文中，我们首先提出了一个新的分类的过渡模式，然后设计了一个新的家庭的CAC基于此分类。与以前的分类相比，我们的分类有更多的类，其类的延迟不重叠，都导致更准确的控制延迟。我们的新的CAC家族包括一些以前提出的代码，以及新的代码，减少延迟和提高吞吐量。因此，这种新的CAC家族提供了总线延迟和效率之间的更广泛的折衷。最后，由于我们的分类和CAC的分析方法将技术相关参数视为变量，因此我们的方法可以很容易地适应各种各样的技术。
The crosstalk delay associated with global on-chip interconnects becomes more severe in deep submicrometer technology, and hence can greatly affect the overall system performance. Based on a delay model proposed by Sotiriadis , transition patterns over a bus can be classified according to their delays. Using this classification, crosstalk avoidance codes (CACs) have been proposed to alleviate the crosstalk delays by restricting the transition patterns on a bus. In this paper, we first propose a new classification of transition patterns, and then devise a new family of CACs based on this classification. In comparison to the previous classification, our classification has more classes and the delays of its classes do not overlap, both leading to more accurate control of delays. Our new family of CACs includes some previously proposed codes as well as new codes with reduced delays and improved throughput. Thus, this new family of CACs provides a wider variety of tradeoffs between bus delay and efficiency. Finally, since our analytical approach to the classification and CACs treats the technology-dependent parameters as variables, our approach can be easily adapted to a wide variety of technologies.
