Concurrency characteristics in DSP programs

The exploration of concurrency has emerged as a dominant research problem in the VLSI DSP literature. A great variety of forms of concurrency exploration have been proposed, analyzed and used on a number of hardware platforms. The belief that the DSP domain is amenable to concurrency exploration has been gaining popularity; however, no systematic study has been conducted to confirm or dispel this claim. This paper presents a global view of the concurrency problem, presenting comprehensive statistics on concurrency properties in commonly used DSP programs. Particular emphasis is placed on the potential cost effectiveness of concurrency exploitation
