Abstract:
1. A method for controlling access to data in a Flash, comprising: outputting at least one main data block to a buffer area of the Flash continuously, the buffer area of the Flash being adapted to buffer data to be output to a storage area of the Flash; generating checksum data for each main data block and buffering the generated checksum data when outputting the at least one main data block to the buffer area of the Flash; outputting the buffered checksum data of the at least one main data block to the buffer area of the Flash; receiving a command of starting write operation from a CPU before outputting the at least one main data block to the buffer area of the Flash; and after the at least one main data block and the checksum data thereof have been outputted to the storage area of the Flash from the buffer area of the Flash, sending an interrupt to the CPU, receiving a state from the CPU, and sending to the CPU state information for indicating whether a write operation is successful.
