This paper summarizes a special session at the Design Automation and Test in Europe Conference on multicore/ multi-processor system-on-chip (MPSoC) programming challenges.
Wireless multimedia terminals are among the key drivers for MPSoC platform evolution.
Heterogeneous multiprocessor architectures achieve high performance and can lead to a significant reduction in energy consumption for this class of applications. However, just designing energy efficient hardware is not enough. Programming models and tools for efficient MPSoC programming is equally important to ensure optimum platform utilization.
Unfortunately, this discipline is still in its infancy, which endangers the return on investment for MPSoC architecture designs. On one hand there is a need for maintaining and gradually porting a large amount of legacy code to MPSoCs.
On the other hand, special C language extensions for parallel programming as well as adapted process network programming models provide a great opportunity to completely rethink the traditional sequential programming paradigm for sake of higher efficiency and productivity.
MPSoC programming is more than just code parallelisation, though. Besides energy efficiency, limited and specialized processing resources, and real-time constraints also growing software complexity and mapping of simultaneous applications need to be taken into account.
In this paper we analyze the programming methodology requirements for heterogeneous MPSoC platforms and outline new approaches.
