Abstract :
The software development and optimization of the communication is presented for an experimental scalable multiprocessor system purposed for multimedia applications. For convenient application mappings, presented C-code primitives hide the communication topology and allow the system to be expanded without needs to rewrite programs. For real-time applications, fast hardware communication need a strong support from software to prevent large latency times. Measured latency times and obtained throughput in communication are compared between user level application and maximum available hardware performance
