Abstract: A processor for performing floating-point operations includes an array of processing elements arranged to enable a floating-point operation. Each processing element includes an arithmetic logic unit to receive two input values and perform integer arithmetic on the received input values. The processing elements in the array are connected together in groups of two or more processing elements to enable floating-point operation.

Abstract: Techniques, systems and apparatus are described for providing a processing element (PE) structure forming a floating point unit (FPU)-processing element. Each processing element includes each of two multiplexers (MUXes) to receive data from one or more sources including another PE, and select one value from the received data. The processing element includes an arithmetic logic unit (ALU) in communication with the two multiplexers to receive the selected value from each multiplexer as two input values, and process the received two input values to generate results of the ALU.

Abstract: A method for wireless communication, and more particularly, a method for reducing the number of temporal connections in Bluetooth devices when obtaining neighboring Bluetooth device names is provided. The method for reducing temporal connections in Bluetooth devices comprises determining whether other Bluetooth devices are present, obtaining a name by temporally connecting to a Bluetooth device whose presence has been determined and determining whether other Bluetooth devices are present after a predetermined time has passed, and then obtaining a changed name through a temporal connection only to other Bluetooth device whose name has been changed. According to the above method, blocking temporal connections to Bluetooth devices whose name has not changed according to changes in the UNDEF field of FHS packets enables a reduction in the frequency of temporal connections.

Abstract: A method of correcting white balance in a video camera is provided, which controls the red gain and blue gain of a captured image signal to allow the average of color difference signals of a picture, the method including the steps of (a) dividing the captured image of one picture into a predetermined number of unit cells, and accumulating the color difference signals by cells divided, (b) extracting an effective cell according as the accumulated data of each of the unit cells is data required for white balance correction or not, (c) judging whether data of the effective cell extracted in step (b) is monochrome data or mixed color data, (d) performing white balance correction without using the effective cell when the data of the effective cell is judged to be mixed color data in step (c), and (e) carrying out white balance correction using the effective cell when the data of the effective cell is judged to be monochrome data in step (c).

Abstract: An analog translator for the IEEE 1394 serial bus by which it is possible to use an analog device as a part of a home network when the analog device is connected to the IEEE 1394 serial bus and a translating method thereof are provided.

Abstract: A bus encoding/decoding apparatus and method for a low power digital signal processor (DSP), which uses a narrow data bus, is provided. The apparatus for encoding n bits of data of a data bus, includes a conditional inverting unit for inverting each of (n−1) lower bits of n data when the most significant bit of the n bits of data is 1, a storage unit for storing the last n bits of data which is output to the bus, and a first exclusive OR operating unit for performing a bitwise exclusive OR operation on the lower (n−1) bits or data, which has been inverted by the conditional inverting unit, and the lower (n−1) bits of the n data, which has been stored in the storage unit, wherein the most significant bit of the n bits of data and (n−1) bits of data, which is obtained as the result of the bitwise exclusive OR operation performed by the first exclusive OR operating unit, are output.

Abstract: A recording apparatus and process for conserving space on a recording medium of a security system includes the steps of detecting a motion amount from the image picked up by a camera, while recording the image, comparing the detected motion amount to a predetermined threshold, and increasing a counted value when the motion amount is equal to or lower than the predetermined threshold, and resetting the counted value when the motion amount is higher than the predetermined threshold, and comparing the counted value to a reset value, and when the former is higher the latter, rewinding until the counted value becomes zero, and then return to the step of detecting a motion amount. Therefore, motion of a recorded image signal is detected and compared. A recorded part is found, in which no motion occurs for a predetermined period of time. Recording is again performed, to overwrite this part where no motion occurred. This increases the available recording time, and economizes use of space of the recording medium.

Abstract: A technique for backlight compensation in a monitoring camera performs automatic backlight compensation without any need for manually redesignating a backlight compensation area, despite changes in ambient illumination, by selecting the most appropriate backlight compensation area for changes in the ambient illumination and the movement of an object from among a plurality of predetermined backlight compensation areas and controlling an iris on the basis of the luminance signal level of the selected backlight compensation area, to thereby control the luminance signal level.
