 * (22): [NEC SX Aurora](https://ftp.libre-soc.org/NEC_SX_Aurora_TSUBASA_VectorEngine-as-manual-v1.2.pdf) is based on the original Cray Vectors
 * (23): [Aurora ISA guide](https://sxauroratsubasa.sakura.ne.jp/documents/guide/pdfs/Aurora_ISA_guide.pdf) Appendix-3 11.1 p508
 * (24): Like the original Cray Vectors, the ISA Vector Length is independent of the underlying hardware, however Generation 1 has 256 elements per Vector register (3.2.4 p24, Aurora ISA guide)
-* (25): If treated as a 1-Dimensional ISA, the 24-bit Prefix expands 200+ scalar instructions to well over a million intrinsics (N **times** M).
-  If treated as a 2-Dimensional ISA there are far less. N prefix intrinsics **plus** M scalar instruction intrinsics, where N is of the order of 10^4 and M is of the order of 10^2.
+* (25): If treated as a 1-Dimensional ISA, and designed badly, the 24-bit Prefix expands 200+ scalar instructions to well over a million intrinsics (N=10^4 **times** M=10^2).
