摘要

CydraTM 5体系结构增加了对一个循环的重叠连续迭代到一个非常长的指令字(VLIW)基的独特支持。这种体系结构允许高度并行的循环执行比向量化更大的循环类，而不需要像VLIW机器的编译器那样展开循环。本文讨论了Cydra 5循环调度模型，支持该模型的特殊架构特性，以及用于充分利用该架构的循环编译技术。

Overlapped loop support in the Cydra 5

The CydraTM 5 architecture adds unique support for overlapping successive iterations of a loop to a very long instruction word (VLIW) base. This architecture allows highly parallel loop execution for a much larger class of loops than can be vectorized, without requiring the unrolling of loops usually used by compilers for VLIW machines. This paper discusses the Cydra 5 loop scheduling model, the special architectural features which support it, and the loop compilation techniques used to take full advantage of the architecture.
