However With VMX/VSX **not available** in the newly-introduced SFFS Compliancy Level, the existing non-VSX conversion/data-movement instructions require load/store instructions (slow and expensive) to transfer data between the FPRs and -the GPRs. Also, because SimpleV needs efficient scalar instructions in +the GPRs. For a 3D GPU this kills any modern competitive edge. +Also, because SimpleV needs efficient scalar instructions in order to generate efficient vector instructions, adding new instructions for data-transfer/conversion between FPRs and GPRs multiplies the savings.
