clock divider

--- Quote Start ---

I second Kaz on this, with a minor modification. I have always used a modulo counter for clock division. So you can use a counter to count the cycles, thus increase it by one each cycle, and once a value is reached, set the clock high. In this way you won't need the adder and subtractor in Kaz's code (incrementor is cheaper in terms of HW).

Hi turhank,

you can count cycles and then raise clken if you are dividing by integer. but in our case it is fractional 83/125 so you can't count 125 of clcok and generate 83 clk en. The modulo adder is itself doing the division of 83/125
