Division with remainder

"Division with remainder" function building block, based on audiorate counters. Eg., the calculation of "6/1" equals 6 samples calculation duration etc.

Dividend and divisor have to be positive-going numbers. A inputted logic high flank engages the calculation. A logic gate goes high when the results (quotient and remainder) are ready, stored in two S/H modules.

A divisor of zero will let the calculation hang in there for ever. (It takes a while to count out infinity Laughing

). Just re-engage with a more "substantial" divisor value.

6,4% cycles count, 9,4% memory.

Addendum: Since the range of the Clavia numerical system is -256 to +256 Clavia units, 256 is the highest possible result. 96000/256 equals 375, so actually you can clock the circuit constantly at 375Hz and always get reliable results. Hey, that's better than the control refresh rate of most synths. Smile
