Utilizing Redundancy for Timing Critical Interconnect

Timing-Driven Interconnect Synthesis

In this chapter we address performance-driven interconnect synthesis, which seeks to optimize circuit performance by minimizing signal delays to critical sinks. Timing-driven wiring geometries are in general quite different from optimal-area (i.e., Steiner) interconnect trees, especially as die sizes continue to grow while feature dimensions steadily shrink. The exposition below focuses on sele...

Onchip Interconnect Exploration for Multicore Processors Utilizing FPGAs

Dual core microprocessors are currently available and higher processor-count architectures will dominate the multicore market. A complex part of these higher order multicore designs will be the interconnection scheme that exists onchip and how exactly that interconnection is best used and configured. While FPGAs currently support a variety of onchip bus interconnects, there is a gap in the tool...

Advisor for Timing - Critical

We describe a \topology advisor" for routing of critical (multi-source) buses in building-block design. The tool accepts as input a block layout, a two-layer routing cost structure superposed over the block layout, terminal locations for a multi-source bus, and source-sink delay upper bound (linear or Elmore delay) constraints for all terminal pairs. The b best routing solutions (b a user param...

افزونگی قاب های موضعی (redundancy for localized frames)

نشان میدهیم افزونگی یک ویژگی کیفی است که قاب های فضای هیلبرت را در کاربرد مفید می سازد. با این حال بدست آوردن یک تعریف کمی معنی دار از افزونگی برای قاب های نامتناهی پیچیده است ولی از آن جایکه جایگزین هایی برای افزونگی موجود است مهمترین مساله باز این است که ایا یک قاب با افزونگی بزرگتر از یک دارای یک زیر قاب با افزونگی دلخواه نزدیک به 1 هست یا نه ؟ ما به این سوال برای قاب های موضعی شده جواب مثب...
