- Yes, it look like it. I also think that the DSP and the CPU excachange
- _alot_ of data so the bus to the DSP might be another bottle neck. I will
- ask Doug of the possibility of an 030/040 only version, or atleast if
- he could do an optimised version that doesn't use the DSP so much as the
- current version does. I guess that depend of how much work it involves and if he
- got the time to do it.
