A Framework for Real-Time Systems Migration to Multi-Cores
Publication Type:
Report - MRTC
ISRN:
MDH-MRTC-235/2009-1-SE
Abstract
Power consumption and thermal problems limit a
further increase of speed in single-core processors.
Processor architects are therefore moving toward multicore
processors. However, a shift to multi-core processors
is a big challenge for developers of embedded real-time
systems, especially considering existing âlegacyâ systems
which have been developed with single-core processor
assumptions. These systems have been developed and
maintained by many developers over many years, and
cannot easily be replaced due to the huge development
investments they represent. In this paper we investigate
challenges of migrating complex legacy real-time systems
to multi-core architectures. We propose a partitioning
algorithm to prepare the migration. Partitioning groups
task and maps them to the different cores on the multicore
processor, increasing system performance while
ensuring correctness. We have run experiments that
compare outputs of the algorithm to the outputs of an
exhaustive search. Based on a cost function, the algorithm
produces systems very close to optimal partitioning with
respect to the cost function.
