    摘要: The present invention relates to a method for determining an optimal frame size for tag collision prevention in an Aloha-based RFID system in which frame sizes limited to a certain unit are used to identify tags, the method including the steps of using an RFID for: (a) calculating an estimated optimal frame value for the RFID reader identifying the tags; (b) calculating expected time delays per tag of a left-hand frame size and a right-hand frame size, which show the smallest differences with respect to the estimated optimal frame value, among the frame sizes; (c) comparing, the expected time delay per tag of the left-hand frame size with that of the right-hand frame size; and (d) determining a frame size which has a smaller expected time delay per tag, between the left-hand frame size and the right-hand frame size, to be an optimal frame size.

    摘要: A method and apparatus for transmitting audio data is disclosed. In the method of sending audio data, audio data to be sent are divided into basic channel audio data and supplementary audio data for services of a high channel. When a left channel or a right channel is selected in response to a word selection signal in accordance with the standards of a serial bus, the basic channel audio data corresponding to a selected channel are sent, and at least one of the supplementary audio data is sent during the remaining time until another channel is selected in response to the word selection signal. Accordingly, audio data of a high channel, such as a 5.1 channel, can be sent without a design change using a serial bus for supporting a 2 channel, such as an I2S bus.

    摘要: Provided are a delay locked loop (DLL), which is capable of being adopted at a data processing system and include a duty correction circuit, and a duty correction method at the DLL. The duty correction method includes generating first and second delay clock signals having different phase shifts by delaying an external clock signal by as much as first and second set phases in response to a delay control signal, generating first and second first signals respectively synchronized with the first and second delay clock signals, and generating an output clock signal having a set duty ratio by using the first and second pulse signals. According to the foregoing, a more accurate duty correction operation is performed without a half cycle time delay line or a matching delay line.
