摘要： The present invention relates to a transmitter and a receiver for speech coding and decoding by using an additional bit allocation method. The transmitter and the receiver according to the present invention realize a voice communication service of high quality by using additional bits permitted in system requirements while using a conventional speech coder as it is. In addition, the transmitter and the receiver according to the present invention have an advantage in that they enable insertion of additional quantization blocks while not changing the structure of the conventional standard speech coder, since they allocate additional bits by applying a multi-stage quantization procedure not in a speech signal domain but in a parameter domain.

摘要： An image-based hand detection apparatus includes a hand image detection unit for detecting a hand image corresponding to a shape of a hand clenched to form a fist from an image input. A feature point extraction unit extracts feature points from an area, having lower brightness than a reference value, in the detected hand image. An image rotation unit compares the feature points of the detected hand image with feature points of hand images stored in a hand image storage unit, and rotates the detected hand image or the stored hand images. A matching unit compares the detected hand image with the stored hand images and generates a result of the comparison. If at least one of the stored hand images is matched with the detected hand image, a hand shape recognition unit selects the at least one of the stored hand images as a matching hand image.

摘要： A DMA controller includes a channel status generator determining whether the state of a channel connected to a peripheral corresponds to the first part of transmission data when receiving a DMA request from the peripheral; an address generator generating addresses of the peripheral and a memory; a control signal generator generating signals representing DMA operation states; and a buffer temporarily storing data from the peripheral and transmitting them to the memory. The address generator generates an address of a register storing a data transmission size of the peripheral when the channel state represents the first part of the data. The control signal generator generates a control signal for receiving a value stored in the register storing the data transmission size.
