%X This paper researches a programmable signal generator by an high integrated direct digital frequency synthe- sis(DDFS) technology on FPGA to simulate servo signal for read-write channel of micro hard disk.This device use very large-scale integrated circuit FPGA(field-programmable logic) to integrate PDSP(programmable digital signal proces- sor) design and DDFS design.Test results indicate that this device has higher precision of signal,and circuit design is simply,reliable,and programmable,Compared with general design by separate parts design.
