We present a framework (real-time calculus) for analysing various system properties pertaining to timing analysis, loads on various components and on-chip buffer memory requirements of heterogeneous…
Context-sensitive timing analysis of Esterel programs
- Lei Ju, Bach Khoa Huynh, S. Chakraborty, Abhik Roychoudhury
- Computer Science46th ACM/IEEE Design Automation Conference
- 26 July 2009
This paper proposes techniques to obtain tight estimates on the processing time of input events by sequential C code generated from Esterel programs and captures program-level contexts across ticks in order to obtain tighter estimates on response times of events whose processing spans across multiple clock ticks.
Performance evaluation of network processor architectures: combining simulation with analytical estimation
Control theory-based DVS for interactive 3D games
A control theory-based dynamic voltage scaling (DVS) algorithm for interactive 3D game applications running on battery- powered portable devices that periodically adjust the game workload prediction based on the feedback from recent prediction errors.
Embedded Software in Network Processors - Models and Algorithms
- L. Thiele, S. Chakraborty, M. Gries, A. Maxiaguine, Jonas Greutert
- Computer ScienceInternational Conference on Embedded Software
- 8 October 2001
A task model for embedded systems operating on packet streams, such as network processors, allows a unified treatment of several problems arising in the network packet processing domain such as packet scheduling, task scheduling and architecture/algorithm explorations in the design of network processors.
Games are up for DVFS
- Yan Gu, S. Chakraborty, Wei Tsang Ooi
- Computer Science43rd ACM/IEEE Design Automation Conference
- 24 July 2006
It is shown using detailed experiments that (surprisingly) interactive computer games are highly amenable to DVFS, and a novel workload characterization of computer games is presented, based on the game engine for Quake II.
A Hybrid DVS Scheme for Interactive 3D Games
This paper proposes a novel DVS scheme that is specifically directed towards interactive 3D game applications running on battery-operated portable devices and has shown very encouraging results when evaluated with different setups.
