ARM optimised memset from Linux. 2006-02-22T18:52:08+00:00 Thom Johansen thomj@rockbox.org 2006-02-22T18:52:08+00:00 e94d2627957e1142c96577197288991debfa0a2d git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8785 a1c6a512-1295-4272-9138-f99709370657

Added memmove() to the rockbox core. C implementation taken from newlib. Fully optimised ASM implementations for SH1 and coldfire, reusing the AMS memcpy code path for forward copying. 2006-02-06T16:00:58+00:00 Jens Arnold amiconn@rockbox.org 2006-02-06T16:00:58+00:00 d036e97d3816ac2bc0eefc57bc033bd5fbbbf0f9 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8601 a1c6a512-1295-4272-9138-f99709370657

Coldfire: Assembler optimised memcpy(), 2.4x...10x (avg. 6.8x) as fast as the C version when copying large blocks within SDRAM. 2005-11-12T23:42:47+00:00 Jens Arnold amiconn@rockbox.org 2005-11-12T23:42:47+00:00 83d3dcfd88ad9dc3ffcf558891458449d3afaf44 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7835 a1c6a512-1295-4272-9138-f99709370657

SH1 memcpy(): Slightly changed loop concept: saved 4 bytes, and the long+1 case is now as fast as the long+3 case. 2005-10-31T01:10:27+00:00 Jens Arnold amiconn@rockbox.org 2005-10-31T01:10:27+00:00 d8ad74de74f89fbbf5b1824b9f01878f7b5679ce git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7696 a1c6a512-1295-4272-9138-f99709370657

Further optimised SH1 memcpy(): Lower latency for very small blocks, faster large block copying for odd destination alignment (+27% for long+1, +33% for long+3). 2005-10-30T20:48:52+00:00 Jens Arnold amiconn@rockbox.org 2005-10-30T20:48:52+00:00 c082bc42a20e8b325cfa0c680d940f5d4e95e2f5 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7690 a1c6a512-1295-4272-9138-f99709370657

Revived C implementations of memcpy() and memset() for platforms without asm optimized versions (gmini), replacing the intermediate strings.c. Moved the asm optimized versions 'out of the way' for the implicit 'make' rules by renaming them to *_a.S (for assembler/alternative). 2005-01-21T22:43:02+00:00 Jens Arnold amiconn@rockbox.org 2005-01-21T22:43:02+00:00 0310f16005a1e98c441221bc0f0f7586d0b19763 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@5628 a1c6a512-1295-4272-9138-f99709370657
