【 摘 要 】

Scientific applications use highly specialized data structures that require complex, latency sensitive graphs of integer instructions for memory address calculations. Working with the Univeristy of Wisconsin, we have demonstrated significant differences between the Sandia's applications and the industry standard SPEC-FP (standard performance evaluation corporation-floating point) suite. Specifically, integer dataflow performance is critical to overall system performance. To improve this performance, we have developed a configurable functional unit design that is capable of accelerating integer dataflow.
