Sine on 218x (preferably 2186) - Martins Pukitis - Jul 15 18:24:00 2002

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.

download it from the ADI web site. Leon

>TIA. I wrote an article on this subject that was published in the ADI DSP
Connection 2002. 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.
