The Message Passing Interface (MPI) standard specifies the use of (source, tag, communicator) tuple to identify whether an incoming message is what the receiver process is expecting. The cost associated with this process, commonly known as "tag matching", is tightly coupled with the communication pattern of the application and the load it generates at each individual process. Although researchers...
Multimedia decoders mapped onto MPSoC platforms exhibit degraded video quality when the critical system resources such as buffer and processor frequency are constrained. Hence, it is essential for system designers to find the appropriate mix of resources, living within the constraints, for a desired output video quality. A naive approach to do this would be to run expensive system simulations of the...
Embedded electronic devices like mobile phones and automotive control units must perform under strict timing constraints. As such, schedulability analysis constitutes an important phase of the design cycle of these devices. Unfortunately, schedulability analysis for most realistic task models turn out to be computationally intractable (NP-hard). Naturally, in the recent past, different techniques...
A new method for two-dimensional (2-D) regional transit time analysis in SiGe HBTs is presented, using a commercially-available TCAD suite with hydrodynamic device simulations. The quasi-static 2-D transit time analysis is first used to determine the cutoff frequency of a well-calibrated 200 GHz SiGe HBT and then applied to the design of hypothetical SiGe HBTs with peak cutoff frequencies of 375 GHz...
The Real-Time Calculus (RTC) framework proposed in [Chakraborty et al., DATE 2003] and subsequently extended in [Wandeler et al., Real-Time Systems 29(2-3), 2005] and a number of other papers is geared towards the analysis of real-time systems that process various types of streaming data. The main strength of RTC is a count-based abstraction, where arrival patterns of event streams are specified as...
