* {1}: plus EXT001 24-bit prefixing. See [[sv/svp64]]
* {2}: A 2-Dimensional Scalable Vector ISA with both Horizontal-First and Vertical-First Modes. See [[sv/vector_isa_comparison]]
* {3}: on specific operations. See [[opcode_regs_deduped]] for full list
-* {4}: SVP64 provides the Vector register concept on top of the **Scalar** GPR, FPR and CR register files.
+* {4}: SVP64 provides the Vector register concept on top of the **Scalar** GPR, FPR and CR Fields, extended to 128 entries.
* {5}: SVP64 Vectorises Scalar instructions. It is up to the **implementor** to choose (**optionally**) whether to apply SVP64 to e.g. VSX Quad-Precision (128-bit) instructions.
* {6}: big-integer add is just `sv.adde`. Mul and divide require addition of two scalar operations
* {7} See [[sv/svp64/appendix]] and [ARM SVE Fault-First](https://alastairreid.github.io/papers/sve-ieee-micro-2017.pdf)
