Abstract: PURPOSE: A system for acquiring digital x-rays image in video for a dental clinic is provided to establish the system offering video image with fast image acquisition and time reduction for processing image by improving the decline of interface speed between systems, which is not considered in a digital X-ray system for a dental clinic, and the decline of speed due to processing video in a software. CONSTITUTION: A digital hardware system for acquiring X-ray image comprises a CMOS(Complementary Metal-oxide Semiconductor) image sensor(210), a ADC(Analog to Digital Converter,220), an image sensor controller(230), an ADC controller(240), a video processing part(250), a system controller(260), a memory controller(270), a SDRAM(Synchronous Dynamic Random Access Memory)(271), a SRAM(Static Random Access Memory)(272), an interface controller(280), a PC interface(290), and a PC(300). The video processing part performs video processing through a digital hardware at high speed to improve the picture quality of the X-ray image. The video processing part removes noise through filtering an intermediate value and corrects pixel which compensates the pixel specificity of a sensor. The method applied to each pixel is pixel correction architecture.

Abstract: PURPOSE: A short distance digital data transceiving device is provided to support a wireless interface by being mounted to a host device with a usual external interface standard. CONSTITUTION: A wireless interface unit(110) converts baseband data into an RF(Radio Frequency) signal and transmits the RF signal. External interface units receive data from the outside. A memory unit(130) stores the data received through the external interface units, the baseband data received through the wireless interface unit, and the baseband data to be converted into the RF signal. A protocol processing unit(140) encodes the data stored in the memory unit into the baseband data.

Abstract: A multiprocessor SoC(System on Chip) platform and a DVB-T(Digital Video Broadcasting-Terrestrial) baseband receiver using the same are provided to realize flexibility while being suitable for fast operation by using a crossbar switch. A first processor(10) such as a main processor manages entire scheduling and manages communication with an external device. At least one second processor(20a-20c) such as a DSP(Digital Signal Processor) processes a digital signal. At least one slave device(30a-30c) communicates with the main processor and the slave processor. A CI(Communication Interface) unit(40) connects the main processor and the slave device in a crossbar switching mode to enable the main processor and the DSP to communicate with the slave device. The CI unit includes a crossbar switch comprising a plurality of unit crossbar cells for forming a communication path between the main processor and the salve device and between the DSP and the slave device according to the crossbar switching mode, and a CI controller forming the communication path to the slave device when at least one of the main processor and the DSP requests access to the slave device depending on a priority policy.
