On my 233MHz StrongArm I saw a reduction in CPU utilisation from 37% with 0.12.3b to 21% with 0.12.4b decoding the same 192kbps mp3. Here's the output of tcsh's "time" command for each:
before: 78.704u 3.579s 3:40.28 37.3% 0+0k 0+0io 162pf+0w after: 43.241u 3.788s 3:40.12 21.3% 0+0k 0+0io 160pf+0w
That's pretty nice. Which StrongARM CPU is that?
Ahh, a SA 110.
On my 220 MHz SA 1100, usage is also now at about 49 MHz.
This weekend I'll be concentrating on a rewrite of the Layer III Huffman decoding and requantization for hopefully even more performance gains.
Cool!
