DATA PROCESSOR AND METHOD FOR DETECTING RESIDUAL DATA AMOUNT OF BUFFER

PROBLEM TO BE SOLVED: To provide a data processor free from incorrect detection of buffer underrun by detecting exact residual amount of buffer data, and to provide a detection method of residual data amount in the buffer. SOLUTION: The data processor which generates and outputs data for recording i...

description PROBLEM TO BE SOLVED: To provide a data processor free from incorrect detection of buffer underrun by detecting exact residual amount of buffer data, and to provide a detection method of residual data amount in the buffer. SOLUTION: The data processor which generates and outputs data for recording in an optical disk based on the data transmitted from a computer device has a command storage section 20 which stores a plurality of control commands which process data stored in a buffer 10 by predetermined area, and detects residual data amounts which can be output based on the sum total value in a field of iteration number of control commands stored in the command storage section 20, the number of data in which a control command is not generated although transmitted from the computer device, and the remaining number of iteration of control command under processing among control commands stored in the command storage section 20.
