Keywords:floating point block? filterbank WOLA? coprocessor? application note?

The WOLA filterbank coprocessor is an integral part of Toccata Plus, BelaSigna 200 and Orela 4500 series products. This application note describes the block floating-point scheme used in the WOLA filterbank coprocessor to preserve numeric precision in time-frequency transform. It is critical to have a good understanding of the WOLA block floating-point mechanism to optimize and plan tradeoffs for the best numeric precision at all processing stages as well as to avoid saturation effects.
