Speex requirements on a TI Davinci / ARM926EJ-Sid(wb)
...ode takes ~243MIPS.
NB decode takes ~10MIPS, encode takes ~102MIPS.
(And by MIPS, I mean ARM CPU cycles, not Dhrystone MIPS)
If I manually (because I couldn't figure out how to make configure do
it) add "-mpcu=arm926ej_s" and "-DSHORTCUTS", the wideband numbers drop
to 22MIPS and 219MIPS, respectively.
