Abstract
Power consumption and thermal problems limit the
single-core processors to be faster. Processor architects
are therefore moving toward multi-core processors.
Developers of embedded real-time systems however
hesitates a shift to multi-core processors, especially for
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 can not 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 componentization and partitioning to prepare the
migration. Componentization groups logically related
tasks into components (or subsystems). This provides an
abstraction layer from a scheduling perspective, which
facilitates migration. Partitioning maps tasks to the
different cores on the multi-core processor, maximizing
system performance while ensuring correctness.
