* QMF filter memory doesn't need to be 32 bits, so convert it to 16 bits. ↵Thom Johansen2007-10-26
| | | | | | Alter assembler code to reflect this. Also do a small optimization in the reverse block copy of the qmf_synth() Coldfire assembler. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15315 a1c6a512-1295-4272-9138-f99709370657

* Further optimised the filter vector math assembly for coldfire, and added ↵Jens Arnold2007-10-25
| | | | | | assembly filter vector math for ARM. Both make use of the fact that the first argument of the vector functions is longword aligned. * The ARM version is tailored for ARM7TDMI, and would slow down arm9 or higher. Introduced a new CPU_ macro for ARM7TDMI. Speedup for coldfire: -c3000 104%->109%, -c4000 43%->46%, -c5000 1.7%->2.0%. Speedup for PP502x: -c2000 66%->75%, -c3000 37%->48%, -c4000 11%->18%, -c5000 2.5%->3.7% git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15302 a1c6a512-1295-4272-9138-f99709370657

| | | | | | always 32 bit aligned, like it is already the case for vector_add() and vector_sub(), for upcoming optimisations. * Un-inline the apply_filter functions for better cache utilisation. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15301 a1c6a512-1295-4272-9138-f99709370657
