~4Dgifts/toolbox/src/swtools/dbcopy README dbcopy.s / ibcopy.s Gianni Mariani 23-Nov-1993 This directory contains a faster version of the memory copy routines than is found in libc in 5.1 and before. dbcopy.s uses the floating point unit as a scratch area while ibcopy.s uses only integer instructions. The 64 bit mode for ibcopy has not been tested. In general ibcopy is about 1.54 x faster on word alignable copies and approx 17 x faster on non aligned copies. There is also a memcpy test program, memtest.c that verifies correct operation of memcpy on random tests.
