An audio synchronization method for Bluetooth speakers is disclosed. The Bluetooth speakers comprise a first Bluetooth speaker and a second Bluetooth speaker transmitting digital audio packets by Bluetooth communication. The method comprises steps of: fetching the sample counts of the first Bluetooth speaker and the second Bluetooth speaker at the first timing; and adjusting the sample rate of the second Bluetooth speaker according to the sample counts of the first Bluetooth speaker and the second Bluetooth speaker. By using the method of the present invention, the sample counts are checked periodically to keep the Bluetooth speakers audio synchronized.

Audio synchronization method for bluetooth speakers

An integrated circuit for executing external program codes comprises a processor, a read only memory for storing program codes of a first routine and a second routine, and a random access memory comprising a first memory block and a second memory block. The processor executes the first routine and uses a plurality of first memory units in the first memory block for accessing data. The processor executes the second routine and uses a plurality of second memory units in the first memory block for accessing data. The first and second memory units comprise one or more common memory units. The processor executes a third routine stored in an external read only memory and accesses the data of the third routine in the second memory block.
