43e94062 – Timothy B. Terriberry <[email protected]> authored and Jean-Marc Valin <[email protected]> committed on 2010/05/29 19:02
Change ec_{enc|dec}_bit_prob to take probabilities in units of 1/65536 instead of 1/256. This allows them to use a single 16x16->32 multiply instead of a 24x8->32 multiply. Also change the time-frequency resolution flag coding to ensure that "0" is always the most-probable symbol (i.e., that prob("1")<50%), as that's where all the rounding error accumulates.

299747ee – Timothy B. Terriberry <[email protected]> authored and Jean-Marc Valin <[email protected]> committed on 2010/05/29 18:47
Provide direct implementations ec_{enc|dec}_bit_prob() that do not require a division instead of using the normal entropy coder path. This should be exactly equivalent to the existing code.
