I've got to make use of some trig functions and sqrt in the ADSP-2184. As you may know this one is sort of memory limited having only 4k pm and 4k dm. I've got a copy of the the applications book for the 2100 family and I just assumed that the nice compact functions given therein would be wrapped in C and made available in VDSP. In looking over the C library math functions provided with VDSP I (finely!) noticed that they are written to use the double (64-bit floating point) format. Being the lazy person I am, Has anyone redone the trig functions to use the fract format? Know of a source? Thanx... |
