Dynamically Reducing Pressure on the Physical Register File through Simple Register Sharing (Best Paper Award)
Using register renaming and physical registers, modern microprocessors eliminate false data dependences from reuse of the instruction set defined registers (logical registers). High performance processors that have longer pipelines and a greater capacity t ...
2004Efficient resource sharing in concurrent error detecting superscalar microarchitectures
Previous proposals for soft-error tolerance have called for redundantly executing a program as two concurrent threads on a superscalar microarchitecture. In a balanced superscalar design, the extra workload from redundant execution induces a severe perform ...
2004Modeling techniques and verification methodologies for substrate coupling effects in mixed-signal system-on-chip designs
The substrate noise coupling problems in today's complex mixed-signal system-on-chip (MS-SOC) brings a new set of challenges for designers. In this paper, we propose a global methodology that includes an early verification in the design flow as well as a p ...
2004Graphical Monitoring of CPU Resource Consumption in a Java-based Framework
Monitoring of CPU consumption is a very basic requirement in many areas of software. It is especially valuable in the frame of Internet applications, in support of specific aspects such as security, reliability and adaptability. This paper is set in the co ...
2004The Lutonium: A Sub-Nanojoule Asynchronous 8051 Microcontroller
James Pugh, Amélie Victoire Martin
We describe the Lutonium, an asynchronous 8051 microcontroller designed for low Et/sup 2/. In 0.18 /spl mu/m CMOS, at nominal 1.8 V, we expect a performance of 0.5 nJ per instruction at 200 MIPS. At 0.5 V, we expect 4 MIPS and 40 pJ/instruction, correspond ...
2003Implicitly-multithreaded processors
This paper proposes the Implicitly-MultiThreaded (IMT) architecture to execute compiler-specified speculative threads on to a modified Simultaneous Multithreading pipeline. IMT reduces hardware complexity by relying on the compiler to select suitable threa ...
2003Dynamically Tuning Processor Resources with Adaptive Processing
The productivity of modern society has become inextricably linked to its ability to produce energy-efficient computing technology. Increasingly sophisticated mobile computing systems, powered for hours solely by batteries, continue to proliferate rapidly t ...
