Width-Sensitive Scheduling for Resource-Constrained VLIW Processors

  title={Width-Sensitive Scheduling for Resource-Constrained VLIW Processors},
  author={Bruce R. Childers},
As the width of processor instruction words increases, so do the opportunities for optimizations that exploit the widths of operands in instructions. This paper presents a feedback-directed technique, called widthsensitive scheduling, that packs operations on a functional unit, thereby enabling sharing of a functional unit among multiple operations. We target this technique as a static optimization to VLIW processors that are are resource-constrained, and use pro le data to guide the… CONTINUE READING
