Sequential specification of time-aware stream processing applications (Extended abstract)

Stream processing applications, and in particular Software Defined Radio applications, are typically executed on multi-core systems. Such applications often have real-time throughput constraints. Automatic parallelization of Nested Loop Programs (NLPs) is an attractive method to create embedded real-time stream processing applications for multi-core systems [1]. However, the description and parallelization of applications with a time dependent functional behavior has not been considered for NLPs. In such a description, semantic information about time dependent behavior must be made available for the compiler, such that an optimized time independent implementation can be generated automatically.
