Hi <BR>
<BR>
When we run the profiler these 3 functions take more than 8500 cycles.<BR>
<BR>
<DIV><FONT class=ecxApple-style-span face="'comic sans ms'">split_cb_search_shape_sign_N1()</FONT><SPAN style="WHITE-SPACE: pre" class=ecxApple-tab-span><FONT class=ecxApple-style-span face="'comic sans ms'"> </FONT></SPAN><FONT class=ecxApple-style-span face="'comic sans ms'">22782</FONT></DIV>

<DIV> </DIV>
<DIV>So can I configure these in a different way so it takes less cycles.</DIV>
<DIV>I do not need very high sound quality</DIV>
<DIV> </DIV>
<DIV>Thanks for your time</DIV>
