Abstract：It has presentd an effective approach to rasie the resource utilization rate of the triggers in the Control Programmable Logic Device（CPLD） by the design skill in digital circuit．The accurate decimal frequency divider is used in the research．The quantity of the trigger used in the circuit is greatly reduced by replacing the high-multiple frequency divider with two low-multiple ones．Its principle is described through the design of the simple music generator and the estimation on the quantity of the triggers is also given．With on increase of the exterior oscillation frequency，the precision of the note frequency is secured．The control and decode sequence is composed with ABLE language．
