Temperature-Aware Design and Management for 3D Multi-Core Architectures

David Atienza Alonso, Mohamed Mostafa Sabry Aly

Vertically-integrated 3D multiprocessors systems-on-chip (3D MPSoCs) provide the means to continue integrating more functionality within a unit area while enhancing manufacturing yields and runtime performance. However, 3D MPSoCs incur amplified thermal ch ...

FireBird: PowerPC e200 Based SoC for High Temperature Operation

Andreas Peter Burg, Yusuf Leblebici, Thomas Maeder, Pascal Andreas Meinerzhagen, Conor Joseph Slater, Ömer Cogal, Carl Christian Sten Dominic Senning, Radisav Cojbasic

PowerPC Architecture microcontrollers are commonly used in embedded applications. In this work we present FireBird, the first PowerPC based SoC for reliable operation beyond 200C. It is a significant challenge to design SoCs for reliable operation at high ...

Robotic goalie with 3 ms reaction time at 4% CPU load using event-based dynamic vision sensor

Conventional vision-based robotic systems that must operate quickly require high video frame rates and consequently high computational costs. Visual response latencies are lower-bound by the frame period, e.g., 20 ms for 50 Hz frame rate. This paper shows ...

Process-induced skew variation for scaled 2-D and 3-D ICs

Giovanni De Micheli, Vasileios Pavlidis, Hu Xu

Technology scaling and three-dimensional integration are two design paradigms that offer high device density. Process variations affect these design paradigms in different ways. The effect of process variations on clock skew for a 2-D circuit implemented a ...

Adaptive multiresolution schemes with local time stepping for two- dimensional degenerate reaction-diffusion systems

Ricardo Esteban Ruiz Baier

Spatially two-dimensional, possibly degenerate reaction–diffusion systems, with a focus on models of combustion, pattern formation and chemotaxis, are solved by a fully adaptive multiresolution scheme. Solutions of these equations exhibit steep gradients, ...

Platform-independent profiling in a virtual execution environment

Philippe Moret

Virtual execution environments, such as the Java virtual machine, promote platform-independent software development. However, when it comes to analyzing algorithm complexity and performance bottlenecks, available tools focus on platform-specific metrics, s ...

Continuous Bytecode Instruction Counting for CPU Consumption Estimation

Andrea Camesi

As an execution platform, the Java Virtual Machine (JVM) provides many benefits in terms of portability and security. However, this advantage turns into an obstacle when it comes to determining the computing resources (CPU, memory) a program will require t ...

A multitasking and data-driven architecture for multi-agents simulations

Sébastien Schertenleib

The expansion of 3D real-time simulations (3DRTS) into millions of homes together with the technical progress of computers hardware force to approach software developments for 3DRTS from different perspectives. From an historical standpoint, 3DRTS started ...
