FIRMWARE DOWNLOAD SCHEME CAPABLE OF ERROR COLLECTION

摘要

A firmware download scheme capable of correcting error is provided to correct the error of firmware downloaded from a host to an electronic device based on an ECC(Error Checking and Correction) and CRC(Cyclic Redundancy Check) bits included in a firmware data signal packet received from the host, thereby increasing integrity of the firmware. An interface(210) receives a firmware data signal including an ECC(Error Correction Code) from the outside. An ECC unit(250) corrects error included in the firmware data signal and stores the corrected data signal to a non-volatile memory(260) such as a flash memory. A buffer(220) temporarily stores the firmware data signal received through the interface. The error correction circuit corrects the error included in the firmware data signal stored in the buffer by control of a CPU(240). A firmware data signal packet received from the outside includes data, and ECC and CRC(Cyclic Redundancy Check) bits.
