摘要： The bit length reducing unit reduces the bit length of an operand expressed by a floating-point number and outputs the operand to a computing unit. The bit length increasing unit increases the bit length of the result value of operation represented by the floating-point number inputted from the computing unit and restores the original bit length. The bit length reducing unit discards a preset number of higher-order bits of the exponent part of the floating-point number and at the same time adds a positive or negative offset value to the exponent part with the higher-order bits discarded, according to an application to be executed by the computing unit. The bit length increasing unit restores the bits discarded by the bit length reducing unit 11 from the exponent part of the floating-point number and at the same time subtracts an offset value from the exponent part.

摘要： An image stabilization control circuit of an image-capturing device prevents overflow of data in an integration process performed in a digital signal process on a signal outputted by a gyro-sensor. A gyro-filter receives, as an input, fixed-point format angular velocity data (Dω) obtained by subjecting an output signal from the gyro-sensor to an analog-to-digital conversion. In the gyro-filter, an input format conversion circuit converts from fixed-point format to floating-point format. A camera shake vibration component is obtained from the floating-point format Dω, is integrated, and data (Dθ) corresponding to an oscillation angle is generated. After a centering process is performed, Dθ is converted from floating-point format to fixed-point format by an output format conversion circuit, and outputted from the gyro-filter. A drive signal for driving an image stabilization mechanism is generated on the basis of the data outputted by the gyro-filter.

摘要： The present invention provides an inexpensive substrate which can realize m-plane growth of a crystal by vapor phase growth. In a sapphire substrate, an off-angle plane slanted from an m-plane by a predetermined very small angle is prepared as a growth surface, which is a template of the crystal, at the time of growing a crystal of GaN or the like, by a polishing process to prepare a stepwise substrate comprising steps and terraces. According to the above-described configuration, even if an inexpensive sapphire substrate, which normally does not form an m-plane (nonpolar plane) GaN film, is used as a substrate for crystal growth, the following advantages can be attained. Specifically, c-axis growth can be carried out from the plane of each step as an a-plane on the terrace by vapor phase growth, which is advantageous in the fabrication of a device, in order to grow an excellent GaN single crystal which has been epitaxially grown so that the m-plane is opposite to the surplane of the terrace, and, in the mean time, the steps become integrated (fused), whereby a device can be fabricated from a substrate of a GaN single crystal having no significant threading dislocation. Further, the use of the m-plane can advantageously eliminate the influence of piezo electric fields.
