Could anyone send me asm code for calculation of 24 (or 32) bit sine (simple fixed point) or tell me in how many processor cycles he managed to stuff it in? TIA. |

Sine on 218x (preferably 2186)

Not sure where it is, but you can download it from the ADI web site.

The basic routines are available at http://www.danvillesignal.com/applications/generator.htm. One of the examples is a 1 Hz resolution generator using 48kHz sampling with double precision (32 bit) math. We have the application running on our ADSP-2186M based DSP-8300 DSP function module. It is available as part of our DSP-8300 developers kit.
