Patent ID: 7711540

Claim:
An in-circuit emulation (ICE) system with a programming function, comprising: a system power supply, which produces a first direct current (DC) voltage for use as a system power; a DC/DC converter, which is connected to the system power supply in order to change the first DC voltage into a second DC voltage and a third DC voltage that are provided for programming an integral circuit, wherein both the second voltage and the third DC voltage are higher than the first DC voltage; a processing device, which has a processor and a parallel/serial converter, the processor performing an in-circuit emulation and executing a programming function, wherein the processor uses the parallel/serial converter to convert programming codes into corresponding programming signals for executing the programming function; a programmer socket, which is connected to the DC/DC converter and the parallel/serial converter in order to receive the programming signals, the second DC voltage and the third DC voltage to accordingly execute the programming function on the integrated circuit plugged in the socket; and a connector, which has a first end connected to the processing device and a second end connected to a target board to thereby drive and receive electrical signals of the target board on performing the in-circuit emulation.
