Multi-core architectures, which have multiple processing units on a single chip, are widely used as a way to achieve higher processor performance. They have potential to deliver increased performance over single-core processors. Multi-core processors have become main stream in processor design. In multiprocessing, only inter task parallelism can be achieved. But, computation-intensive real-time systems must exploit intra-task parallelism to take full advantage of multi-core processing. In this paper, the problem of scheduling periodic parallel tasks with implicit deadlines on multi-core processors is addressed. A task decomposition method that decomposes each parallel task into a set of sequential tasks is discussed.
