Shared memory and message passing are traditional parallel programming models used on multiprocessor system-on-chip environments. Underlying models are traditionally meant for static scenarios where all communicating entities and their intercommunication patterns are known a priori by the software engineer. The systems design following such programming models became complex due to dynamic behavior of applications at runtime. The goal of this work is to incorporate a publish-subscribe programming model to an MPSoC framework to decouple, in the time and space, the application development. The modified MPSoC framework is composed of a FreeRTOS kernel running on homogeneous processing elements distributed into a network-on-chip. The results present reduction around of 2% to 30% in DTW application execution time, and low overhead in memory footprint when comparing the original MPI primitives with the publish-subscribe programming model.
