摘要： An test circuit and method for testing an integrated device having an embedded function and a built-in test circuit for testing the embedded function. The built-in test circuit provides control signals to the embedded function based upon an internal state of the built-in test circuit. The integrated device is tested by comparing the control signals provided to the embedded function to the desired control signals based upon the internal state of the built-in self test circuit to confirm the proper operation of the built-in self test circuit. The internal state of the built-in test circuit is monitored and the control signals provided to the embedded function are monitored. The monitored signals are compared to an expected signal pattern based upon the monitored internal state of the built-in test circuit. An error signal is generated if the comparison determines that the monitored control signals do not correspond to the expected signal pattern.

摘要： Disclosed is a syntax parser for a video decoder for MPEG2 and includes: a shift register which executes the shift operation after receiving MPEG video bitstream; a ROM which stores a program decoding variable length and controlling the hardware operation, and outputs the micro-instruction according to an address; a counter which controls the address of the ROM; a register which stores parameters for decoding MPEG video; a flag controller which generates the flag from a particular code included in the bitstream or the combination of parameters, and outputs the flag; a memory which stores the table related to variable length decoding; and a length controller which gets length information to be shifted from the memory, the micro-instruction or the output of the register. The syntax parser for a MPEG2 video decoder can execute VLD and parse the MPEG bitstream. Using micro-instructions to perform the parsing function decreases the decoding time for the bitstream and obtains the parsing speed corresponding to the MP@HL of the HDTV (high definition television) standard.
