A Ubiquitous Processor Built-in a Waved Multifunctional Unit

In developing cutting edge VLSI processors, parallelism is one of the most important global standard strategies to achieve power conscious high performance. These features are more critical for ubiquitous systems with great demands for multimedia mobile processing. Then, one of most important issues for ubiquitous systems is instruction scheduling, because floating point units indispensable for multimedia mobile applications take longer latency than integer units. Although software parallelism has been inevitable to fully utilize hardware parallelism between regular scalar units, it has been really awkward.
