  • Publication number: 20170123680
    Abstract: Disclosed is a method of recording variable size data. A first processor receives, from a second processor, a read parameter including information on a read address value of data which has been read by the second processor and is stored in an external memory, compares the read address value acquired from the received read parameter and a record address value for data previously recorded in the external memory by the first processor, and determines whether or not the first processor is to transmit data to the second processor on the basis of the comparison result, thereby being capable of reducing the load consumed in controlling variable size data and efficiently utilizing a limited memory.
