Towards an Efficient Approach for Resource Sharing in Real-Time Multiprocessor Systems

Conference/Workshop Paper

Abstract
Supporting resource sharing in multiprocessor architectures
is one of the problems which may limit the benefits
that can be archived using this type of architecture. Many
approaches and algorithms have been proposed to support
resource sharing, however, most of them impose either high
blocking times on tasks or require a large memory size.
In this paper we investigate the possibility of combining
the lock-based approaches and wait-free approaches (using
multiple buffers) in order to decrease both the blocking time
that may affect the schedulability of tasks and the required
memory. To achieve this, we propose a solution based on
evaluating the maximum allowed blocking time on each task
according to the schedulability analysis, and then find the
minimum memory requirement for each resource such that
it limits the blocking times on tasks to be less than the maximum
allowed blocking times.
