One of the main reasons is that cores share access to the main memory, and contentions on the memory bus cause execution delays. Multi-phase task models, where computations phases and communication phases are separated (such as PREM and AER), have been proposed to both mitigate these delays and make them easier to analyze. In this paper we present a compilation process, part of the Prelude compiler, that automatically translates a high-level system specification, consisting in a set of periodic tasks with data-dependencies, into a C program that operates according to the AER multi-phase model. The generated C program is targeted for a multicore platform with distributed memory and includes code to perform communications between the different memories of the platform.Show less >
