摘要
Disclosed are embodiments of a method and system for calculating an unrolling factor for software loops. The unrolling factor may be calculated by applying a formula that takes into account issue constraints of a processor. The issue constraints may include the total issue width of the processor, and may also include individual issue constraints for each instruction type. The software loop may be unrolled by the calculated unrolling factor and may be software pipelined. Other embodiments are also described and claimed.
