On-chip supply boosting can quickly restore a microprocessor core's power rail from near-threshold to super-threshold when critical code sections are encountered. We demonstrate a flip-chip implementation of a supply boosting technique, called …
Energy-efficient near-threshold design has been proposed to increase energy efficiency across a wide range of applications. This article first provides a background motivating near-threshold and how it differs from super-threshold and subthreshold …
Supply-voltage scaling has stagnated in recent technology nodes, leading to so-called dark silicon. To increase overall chip multiprocessor (CMP) performance, it is necessary to improve the energy efficiency of individual tasks so that more tasks can …
Fast boosting of supply rails is critical for near-threshold computing to overcome serial code bottlenecks. A novel supply boosting technique, called Shortstop, boosts a 3nF core in 26ns while maintaining acceptable supply voltage droops. The innate …
We propose Bubble Razor, an architecturally independent approach to timing error detection and correction that avoids hold-time issues and enables large timing speculation windows. A local stalling technique that can be automatically inserted into …
Thirty-four undergraduates implemented a MIPS R2000 processor for an introductory CMOS VLSI design course. This included designing a microarchitecture in Verilog, developing custom PLA generation and ad-hoc random testing tools, creating a standard …
