Scalar happens to set that loop size to one. -The important insight from the above is that, strictly speaking, Simple-V is not really a Vectorisation scheme at all: it is more of a hardware ISA "Compression scheme", allowing as it does for what would normally require multiple sequential instructions to be replaced with just one. This is where the rule that Program Order must be preserved in Sub-OC execution derives from. However in other ways, which will emerge below, the "tagging" concept presents an opportunity to include features definitely not common outside of Vector ISAs, and in that regard it's definitely a xlass of Vectorisation. +The important insight from the above is that, strictly speaking, Simple-V is not really a Vectorisation scheme at all: it is more of a hardware ISA "Compression scheme", allowing as it does for what would normally require multiple sequential instructions to be replaced with just one.
