Interesting piece on the distortion. Here is another thought. I have a design that uses lookup tables(different chip) for distortion modeling. The arctan function is also very nice for soft soft clipping......
For a 16-bit data converter you only need 128k for a fully populated table.

There are actually several applications but here is one: Most EQs/Filters have a control element that controls the amplitude of a shelf/Band (in the case of EQ) or the Q/bandwidth (Parametric) . Consider 2 different filters, let's say each are 2 casacaded bi-quads. Each filter has a handfull of pole...

External Program Memory
Does the FV-1 access the external program memory on every instruction or does it download all of the program code into an internal memory and then execute (and never access the external memory again)? I am planning on doing something crazy like dynamically changing the FV-1 program on the fly (To im...

Delay RAM - 14-bit Compress
I have alot of experience with high end DSPs (TI C6713 for example) but have been looking for a device such as this one for a tiny application. I do have one question about the Delay RAM. I read in the knowledge base that the ADC is 24-bit but the Delay RAM is a 14-bit floating point format. Now, wh...
