Low Power Microarchitecture with Instruction Reuse
Power consumption has become a very important metric and challenging research topic in the design of microprocessors in the recent years. This work improves power efficiency of superscalar processors through instruction reuse at the execution stage. A new method for reusing instructions that compose small loops is proposed: instructions are first buffered in the Reorder Buffer and reused afterwards without the need for dynamically unrolling the loop, as commonly implemented by the traditional instruction reusing techniques. In order to evaluate the proposed method we modified the sim-outorder tool from Simplescalar and the Wattch Power Performance simulators. Several different configurations and benchmarks have been used during the simulations. The obtained results show that by implementing this new method in a superscalar microarchitecture, the power efficiency can be improved without significantly affecting neither the performance nor the cost.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
