The project started with transcoding g.711u to signed linear and the<br>
reverse. It was thought that performing other transcoding operations<br>
would be reasonably represented by this.<br>
</blockquote><div><br>Huh ?<br><br>G711.u / G711.a <=> signed linear transcoding is a trivial table lookup with no arithmetic workload whatsoever. It does not represent the CPU-intensive transcoding operations such as G729 / iLBC / speex, which could benefit from GPU implementations, nor any video codec.<br>
<br>A GPU implementation of G711<=>linear transcoding is probably wasting more instructions to transfer data from and to the GPU board than required to perform the transcoding in loco.<br><br>-- Felipe Bergo<br><br>
