Townsend) Newsgroups: comp.sys.m88k Subject: Big Endian vs. Little Endian register pairs Message-ID: <1991Apr30.185908.16474@eagle.lerc.nasa.gov> Date: 30 Apr 91 18:59:08 GMT Sender: news@eagle.lerc.nasa.gov Distribution: na Organization: Nasa Lewis Research Center ( Cleveland ) Lines: 12 Originator: fsset@bach.lerc.nasa.gov Just curious: does anyone know what the arguments were for/against the register pairing scheme? It just occured to me that if the pairing scheme was reversed (i.e. r1,r0 rather than r1,r2) then we'd save a cycle loading many floating-point constants in preparation for fadd & friends. This would of course look Little-Endian in a register dump :-( -- ------------------------------------------------------------------------ Scott Townsend | Mail Stop: 5-11 NASA Lewis Research Center | Email: fsset@bach.lerc.nasa.gov Cleveland, Ohio 44135 |
