2011-06-24SPC Codec: Restore correct FIR buffer alignment when an address mask is ↵Michael Sevakis
used. It must be FIR_BUF_ALIGN. Fix Coldfire assembly constraint where an input parameter was also being written. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30063 a1c6a512-1295-4272-9138-f99709370657

2011-05-15FS#12113: Optimize IRAM configuration for SPC. Performance increases by 5-6% ↵Andree Buschmann
on PP5022, PP5024 and S5L870x. No change of performance on Coldfire, PP5002 and PP5020. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29887 a1c6a512-1295-4272-9138-f99709370657
2010-12-23SPC Codec: Was broken on ARMv6 since EABI switch and somehow I failed to ↵Michael Sevakis
notice in the first place (and so did eveyone else it seems :). Some early-clobber constraints were needed on inline assemebly operands. In some places, they aren't necessary where they were used, so remove those. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28880 a1c6a512-1295-4272-9138-f99709370657
2010-06-04SPC codec: The inline asm 'memory' clobbers should be unneeded since the ASM ↵Michael Sevakis
either does not modify memory (only loads values), or it modifies things only other ASM blocks deal with and the operand constraints mark them as in/out/both. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26538 a1c6a512-1295-4272-9138-f99709370657

2010-05-02Do some SPC codec optimizing for ARMv6 (as a training exercise), tweak ↵Michael Sevakis
realtime BRR for all CPU that use it, add Gaussian ASM optimization for all ARM that can use it. Add some LIKELY/UNLIKELY branch hints. On Gigabeat-S gives +22% speedup. For Gigabeat F, about +5% speedup. For less-powerful players, no real change aside possibly from branch hints. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25771 a1c6a512-1295-4272-9138-f99709370657
