Syntax parsing apparatus with multiple syntax parsing circuits for processing multiple image regions within same frame or processing multiple frames and related syntax parsing method

A syntax parsing apparatus comprising:

• a plurality of syntax parsing circuits, each having at least entropy decoding capability, wherein the syntax parsing circuits are arranged to generate a plurality of entropy decoding results of a plurality of frames, respectively;
• and
• a dispatcher, arranged to assign bitstream start points of the frames to the syntax parsing circuits and trigger the syntax parsing circuits to start entropy decoding, respectively;
• wherein the syntax parsing circuits comprise:
• a first syntax parsing circuit, arranged to perform entropy decoding upon a first frame included in the frames during a first processing time period;
• and
• a second syntax parsing circuit, arranged to perform entropy decoding upon a second frame included in the frames during a second processing time period, wherein the second processing time period is overlapped with the first processing time period.
