* @log
*   - 2004.04.02 : insert compile options & implement high quality (ver 2.1)
*   - 2004.03.20 : code size down & mips up<quality up(a little)> (ver 2.0)
*   - 2004.02.10 : add 'PSconFunc' function (ver 1.2)
*   - 2004.02.04 : revision (ver 1.1)
*   - 2003.10.11 : complete (ver 1.0)
*   - 2003.09.20 : start code generation
* @mips (ref. Fs=44.1kHz, STEREO, about 288000-samples Tested) : data dependent
*  --> For more details, refer to "code_summary.txt" file.
*      (High-Quality option & Worst Case Condition)
*  <1> Pitch Control
*      --> about  MP3-14.5 / MPG-16.1 / WMA-13.8  MIPS
*  <2> Speed Control : final mips = result(mips)/rate(fast or slow)
*      --> about  MP3-24.1 / MPG-27.6 / WMA-22.5  MIPS
*  <3> Pitch & Speed Control : final mips = result(mips)/rate(fast or slow)
*      --> about  MP3-37.3 / MPG-42.2 / WMA-34.8  MIPS
