DEVICE AND A METHOD FOR PROCESSING DATA OF A DISK DRIVER, PARTICULARLY CONCERNED WITH EFFECTIVELY ACCESSING A MEMORY WHEN DATA IS REPRODUCED IN THE DISK DRIVER

摘要

PURPOSE: A device and a method for processing data of a disk driver are provided to perform ECC/descrambling/EDC processes for demodulated data during a data processing, and to store data by using one-time memory access time to reduce the number of memory access times, thereby improving the usage efficiency of a memory. CONSTITUTION: A demodulator(401) demodulates a received RF signal, and stores the demodulated signal in a memory through a data bus(402) and an MMU(403). An ECC/descrambling/EDC unit(404) reads the demodulated data stored in the memory to perform an ECC process, and generates a scrambling value for the demodulated data. The ECC/descrambling/EDC unit(404) descrambles the data by using the scrambling value and ECC data, and stores the descrambled data in the memory.
