The topic of this research is the interaction between algorithms, fabrication technology, packaging, and CAD (computer-aided design) tools in a very fast arithmetic processor. The investigators are building a multi-function arithmetic processor that can do floating point arithmetic as well as higher level functions (trig, log, etc.). The processor is constructed in BiCMOS (bipolar complementary metal oxide semiconductor), and is packaged on an active silicon substrate that contains etched interconnection lines and active devices for configuring the lines. New CAD tools are needed to allow estimation and matching of delays in the logic blocks and the interconnection.

本研究的主题是非常快速的算术处理器中算法、制造技术、封装和 CAD（计算机辅助设计）工具之间的交互。 研究人员正在构建一个多功能算术处理器，可以执行浮点算术以及更高级别的函数（三角函数、对数函数等）。 该处理器采用 BiCMOS（双极互补金属氧化物半导体）构建，并封装在有源硅衬底上，该衬底包含蚀刻互连线和用于配置互连线的有源器件。 需要新的 CAD 工具来估计和匹配逻辑块和互连中的延迟。
