A device and method for debugging an embedded system are provided. A host system ( 100 ) includes: a user interface ( 110 ) for managing an interface with a user; a debugging engine ( 120 ) for performing a debugging process; and a JTAG command generator ( 130 ) for receiving an information necessary for the debugging process from the debugging engine ( 120 ) and generating a corresponding debugging command. A JTAG signal generator ( 200 ) converts the debugging command inputted from the host system ( 100 ) into a JTAG signal. A target system includes: a TAP for decoding the JTAG signal; and a microprocessor ( 320 ) for receiving the decoded debugging command through the TAP controller ( 310 ) and executing a necessary information and a debugging command. Accordingly, software for the embedded system can be debugged at a low cost by using a PC without any special hardware.
