* Fix the simulator build.Eric Laurent2010-08-251-0/+2
| | | | | | Fixes the sim build broken by commit 58d3bd08107f44cba79938dd8430e69c0fda4202. Change-Id: I5a63623363d558783dc5254fdd322080cc2f3525
* Visualizer: replace the FFT implementation with a faster one.Chia-chi Yeh2010-08-191-0/+160
This implementation uses fixed points instead of floating points. It is slightly inaccurate compared to the old one but still perfect for visualization purpose. It runs 40% faster on passion, 5 times faster on sholes, and of course 14 times faster on sapphire. Change-Id: I1e868417bcffda091becf106a7b941d02813faec
