摘要： In a back electromotive force phase detecting device, a timing generating unit generates a timing signal indicating a start timing, an intermediate timing and an end timing of a 180-degree electrical angle period in a detection target phase, from an excitation pulse signal. A difference calculating unit receives the timing signal, and calculates a difference between a total PWM control period of the detection target phase during a first-half 90-degree period, and a total PWM control period of the detection target phase during a second-half 90-degree period. In an excitation control device, a control unit changes the capability of driving a motor based on an output of the back electromotive force phase detecting device.

摘要： Problems with accuracy reading position detection signal peaks and minute phase differences in the detection current make motor drive control easily susceptible to differences in motor characteristics. The rotor position is determined based on whether or not a neutral point difference voltage, which is the difference voltage between the neutral point voltage and the pseudo-neutral-point voltage when the motor phases are selectively energized, exceeds a specific threshold value. The phase energized to start the motor is determined based on this determination and the motor is energized accordingly to start. Instead of switching directly from the search step at the initial rotor position to the back-EMF voltage mode, a search and start mode that creates initial rotor speed sufficient to start the motor is executed before entering the back-EMF voltage mode.

摘要： The initialization operation time is substantially reduced to realize a high-speed nonvolatile semiconductor memory. A memory array of a nonvolatile semiconductor memory includes a data storage area in which data is stored, a program storage area in which programs are stored, and a table block in which an address translation table for the program storage area is stored. When the program storage area is set at power-on reset of a memory device, an address translation table of the table block is read and the status is ready in which another program storage area is readable. Subsequently, an address translation table for a relevant data storage area is generated by performing an initialization operation of the data storage area, and thus to make the data storage area accessible.

摘要： An information processing device is provided in which a valid initial program is transferred to a RAM while avoiding a invalid block which is present in a low reliable storage device, such as a NAND-type flash memory or the like. A management information storing section 29 stores management information 30 indicating a position of a invalid block in a first storage device 31. When an information processing device 1 is powered on, a transfer determination section 20 is controlled to read a BSP 26 from a valid block of a first storage device 11 based on the management information 30, and transfer the BSP 26 to a second storage device 32. Thereby, it is possible to avoid reading of a invalid block present in the first storage device 31.

摘要： Optical disc drives designed for reduced power consumption switch the supply voltage in three stages between first, second, and third power supplies. The reduction in power consumption that is possible in the focusing and tracking drive circuits with three stage switching control is limited. This drive apparatus enables further reductions in power consumption. A drive output tracking signal is generated according to the drive conditions of the focusing or tracking drive circuit. The drive output tracking signal is applied to the drive circuit power supply, and the power supply is controlled according to the drive output tracking signal. A power supply change detector detects sudden changes in the drive output tracking signal, and inputs the detection signal to the DSP controlling the entire system. The DSP determines whether to improve the power supply response by comparison with predetermined conditions, and returns the result to the power supply.
