  • Patent number: 7120812
    Abstract: A power supply control apparatus for reducing the frequency of running a specific process in an electronic device when the device power turns on or off too soon after being turned off by monitoring the operating state of the power switch. When the power supply control apparatus detects an operation turning the power to the hybrid processing apparatus 1 off, the power supply control apparatus continues supplying power for as long as needed to complete a given shutdown process. However, if the power supply control apparatus 50 detects an operation turning the device power on again after the power supply stops but before reaching a predetermined reset voltage a reset and restart command is applied to the electronic device.

  • Patent number: 6907480
    Abstract: A data processing system enables faster exchange of data between data processing units having a CPU, and simplifies the writing of a data exchange program for the data processing units. A data processing apparatus 3 has a communication unit 4 with a first storage unit 31 and a second storage unit 32. The first storage unit 31 is used for sending data from the first data processing unit 1 to the second data processing unit 2. The second storage unit 32 is used for sending data from the second data processing unit 2 to the first data processing unit 1. Data can therefore be asynchronously exchanged between the data processing units without coordinating control of CPU operations in the data processing units, and control of data communication between the data processing units is simplified.

  • Patent number: 6847180
    Abstract: Control data is efficiently serially transferred to a drive device for driving a motor without involving the CPU. Data buffers are allocated at specific memory addresses. An address decoder decodes a memory address output to the address bus and applies a write enable signal to the corresponding data buffer to write data to that data buffer by DMA transfer. When data is written to a data buffer, a sequencer circuit compiles control data, based on data in that data buffers, in a shift register, and serially transfers the control data one bit at a time on a serial transfer line synchronized to a clock.
