Resource Manager for Non-preemptive Heterogeneous Multiprocessor System-on-chip
Increasingly more MPSoC platforms are being developed to meet the rising demands from concurrently executing applications. These systems are often heterogeneous
with the use of dedicated IP blocks and application domain
specific processors. While there is a host of research done
to provide good performance guarantees and to analyze applications for preemptive uniprocessor systems, the field of
heterogeneous, non-preemptive MPSoCs is a mostly unexplored territory. In this paper, we propose to use a resource
manager (RM) to improve the resource utilization of these
systems. The basic functionalities of such a component are
introduced. A high-level simulation model of such a system
is developed to study the performance of RM, and a case
study is performed for a system running an H.263 and a
JPEG decoder. The case study illustrates at what control
granularity a resource manager can effectively regulate the
progress of applications such that they meet their performance requirements.
