It is widely recognized that current programming techniques, including those that are used for scientific parallel programming, will not allow the easy formulation of general purpose applications. An area which is receiving interest exploiting the BLP, since 1) the total number of banks is significantly larger than those of the channels and ranks in memory systems and thus BLP exploits higher parallelism than the others and 2) the implementation for exploiting one-level parallelism is much simpler than that for exploiting the nested parallelism, i.e.

By storing subsets of the task pool in the local memories of the Synergistic Processing Elements (SPEs), access latency and thus overheads are greatly reduced. Our experiments show that only a worker-centric runtime system that utilizes the SPEs for both task creation and execution is suitable for exploiting fine-grained :// instructions statically and exploit the available parallelism.

This makes VLIW architectures, with their simpler control units, a more cost-effective choice than superscalar architectures in embedded systems. VLIW architectures are also better suited for exploiting parallelism in ?doi=&rep=rep1&type=pdf.
