Resumen
With the popularization of the multi-core architectures and the complexity added by
this archtecture on the development of real-time systems, most of the developed solutions
for the task mapping issue in the current literacture have been focusing on the task
processing distribution. In certain multi-core architectures, like NoCs (network on chip), the
inter task communication, a factor that exerces great influence on the temporal behavior of a
system, is not being take into account. In this paper solution search algorithms will be used
with the objective of developing task mapping techniques that focus on both processing and
communication. For that matter, a group of heuristics were developed, based on key factors
on the temporal behavior of a real-time system. This paper will focus on the NoC
architecture. Throught the utilization of this method on a taskset designed to impose
dificulties on the task mapping process, mappings near to completly scheduable were
obtained proving this altertative to be viable to adress the problem.
