Due to the limitations of current operating systems in supporting multimedia applications, much work has been done to provide resource management mechanisms to address this problem. As processor cycles are often the most oversubscribed and critical resource, most of this work has focused on uniprocessor scheduling. However, hardware platforms are moving to multiprocessor systems, and little wor...

This paper addresses processor design issues for multiprocessor architectures. We assert that some architectural features desirable for a uniprocessor are not as eeective in a multiprocessor. Issues aaecting processor design include granularity, degree of parallelism, cache and network eeects, and dynamic load balancing. We show that using single-instruction-issue processor with dynamic instruc...

We present a framework for modelling and performance estimation of multiprocessor embedded systems. It consists of components for modelling parallel software and multiprocessor hardware; and Systemcbased tool for simulation and performance estimation. The components model are a transactional level description of hardware and software, where timing properties are modelled as annotations on the c...

The reliance on Network-on-Chip (NoC)-based Multiprocessor Systems-on-Chips (MPSoCs) is proliferating in modern embedded systems to satisfy the higher performance requirement of multimedia streaming applications. Task level coarse grained software pipeling also called re-timing when combined with Dynamic Voltage and Frequency Scaling (DVFS) has shown be an effective approach significantly reduc...

A Multistage Interconnection Network (MIN) makes it possible to build large-scale shared-memory multiprocessor systems. To provide insight into dynamic system performance, we have developed an integrated data collection, analysis, and data visualization environment for a MIN-based multiprocessor system, called MIN-Graph. MIN-Graph is a graphical instrumentation monitor to aid users in investiga...
