9320325克里希纳该奖项资助的设备将用于几个研究项目，特别包括以下项目：(1)用于数字信号处理的超大规模集成电路算术阵列：正在开发用于分析和比较不同抽象级别的设计备选方案的方法和工具。部分工作包括利用马萨诸塞州微电子中心和MOSIS的制造设施实施芯片设计。(2)采用Wave流水线的高性能VLSI综合：Wave流水线是一种以前用于手工设计的定制电路设计方法。这项技术正在被纳入用于自动综合高性能VLSI电路的CAD工具中。(3)可测试的非扫描时序电路：正在进行时序电路的设计和开发方法，以便能够检测到大多数路径延迟故障。为避免性能下降，为增强可测试性而添加的任何电路都不允许出现在功能路径中。(4)实时分布式系统的重构：重构是提高分布式系统性能的有力手段。目前，它在很大程度上仅用于对组件故障做出反应。在这个项目中，正在开发一些技术来根据当前的工作量来配置系统，以便优化性能。(5)提高成品率的拓扑和物理版图设计技术：集成电路中集成度和芯片尺寸的提高增加了对成品率提高的需求。在该项目中，正在开发设计技术以提高较大芯片的成品率，以便充分受益于更高水平的集成的优势。*(KT 3COM t WINA20 386`$AUTOEXEC33 XT V LM VW@$CONFIG BAK V CONFIG OLD NW WIN31 X 9320325 KRISHNA此奖项资助的设备将用于多个研究项目，尤其包括Z\u w{$G时报符号“Helvetica芝加哥时报新罗马字母&amp；Arial 5信使新R ZapfDingbats Palatino希腊语GenMath MathMeteor MT Extra“f EDJ 6 Krishna/U MassMark Purvis Mark Purvis

9320325 Krishna The equipment funded by this award will be used for several research projects, including in particular the following: (1) VLSI Arithmetic Arrays for Digital Signal Processing: Methodologies and tools for analyzing and comparing design alternatives at various levels of abstraction are being developed. Part of the work consists of implementing chip designs using the fabrication facilities of the Massachusetts Microelectronics Center and MOSIS. (2) High-Performance VLSI Synthesis with Wave Pipelining: Wave pipelining is a custom circuit design method which has previously been used in hand-crafted designs. This technique is being incorporated in CAD tools for the automatic synthesis of high-performance VLSI circuits. (3) Testable Non-Scan Sequential Circuits: Design and development methodology for sequential circuits are being done so that most path delay faults can be detected. To avoid performance degradation, any circuitry added to enhance testability is not allowed to be in functional paths. (4) Reconfiguration of Real-Time Distributed Systems: Reconfiguration is a powerful method to improve the performance of distributed systems. Currently, it has largely been used only to react to component failures. In this project, techniques are being developed to configure the system as a function of the prevailing workload so that the performance is optimized. (5) Topological and Physical Layout Design Techniques for Yield Enhancement: The greater integration levels and die sizes in integrated circuits have increased the need for yield enhancement. In this project, design techniq ues are being developed to improve the yield of larger chips, so as to fully benefit from the advantages of higher levels of integration. *** ( kT 3COM t WINA20 386 ` $ AUTOEXEC33 Xt V LM VW @$ CONFIG BAK V CONFIG OLD nW WIN31 X 9320325 Krishna The equipment funded by this award will be used for several research projects, including in particular the Z \ u w { $ $ $ $ G Times Symbol " Helvetica Chicago Times New Roman & Arial 5 Courier New R ZapfDingbats Palatino Greek GenMath MathMeteor MT Extra " f eDj 6 Krishna/UMass Mark Purvis Mark Purvis
