M SHUJA AHMED (UNITED KINGDOM)
I am trying to do SURF feature detection and matching. The code was taking more than one minute to execute on BF537.
I used fast floating point operation which reduced the execution time to half. Now I am using fixed point operation.
With fract32 1.31 format, data between +1to -1 can be represented. In my code, I have many operations in which some integers are multiplied with floating point data. I need to find a way in which data outside +1 to -1 range can be represent in fixed point format. Any suggestion?

i'm not sure how many people you'll find here that are familiar with using the fract code. you might want to try posting your question here:
this forum tends to be focused on the Linux side of things rather than pure Blackfin optimization.
