PURPOSE: A single/multiple emulating apparatus is provided to easily emulate a processor each board by operating a jumper switch and a dip switch before a power supply of a system is on, by connecting and separating an emulator signal line between boards. CONSTITUTION: The first board(100) connects to the first DSP(110) which processes digital data, and to an input/output terminal of the first DSP(110). A header pin(120) in a JTAG Pod emulates the first DSP(110). A jumper(JP1) controls an output of the first board(100). The second board(140) connected with the first board(100) in a daisy chain form processes the digital data. If the jumper(IP1) is turned off, the header pin(120) mounted in the first board(100) is connected to the second DSP(150) of the second board(140). If the jumper(JP1) is turned on, the first DSP(120) and the second DSP(150) are not connected each other.
