摘要： The present invention provides a data transmitting/receiving apparatus that determines according to a signal strength of a received radio wave whether a receiving operation should be continued, and a control method thereof. In the data transmitting/receiving apparatus, a measurement unit in a transmitter-receiver counts demodulation clocks of a demodulator. The measurement unit supplies a result of measurement indicating instability of reception data until the counted number thereof reaches a predetermined target count value and indicating stability of the reception data after its attainment to a determinator. When the determinator receives the result of measurement indicative of the instability of the reception data therein, the determinator outputs a result of determination indicative of the stop of a receiving operation regardless of a signal strength. When the determinator receives the result of measurement indicative of the stability of the reception data therein, the determinator outputs a result of determination corresponding to the signal strength of the reception data. Thus, the present apparatus is capable of advancing its receiving operation after the reception data sent from the demodulator is made stable sufficiently.

摘要： An integrated circuit includes a volatile memory, a central processing unit that normally operates on a first clock, and an input-output circuit that transfers data in synchronization with a second clock having a lower frequency than the first clock. The integrated circuit has a power-saving mode in which the volatile memory loses its data and the central processing unit stops operating. The power-saving mode is preceded and followed by transitional periods during which the central processing unit uses the input-output circuit to save data from the volatile memory to an external memory device and restore the data from the external memory device to the volatile memory. During these transitional periods, the central processing unit operates on the second clock to conserve power.

摘要： Wireless communications apparatus is provided by which power consumption is much more reduced in a wireless system composed of a base station and wireless terminal stations. The apparatus installed in the base station includes a transmitter/receiver and a controller. The transmitter/receiver compares an RSSI value indicating the received wave strength of a received wireless signal with a preset value periodically at time intervals set in a timer for defining a time to start and stop the controller. When the RSSI value indicates that the received wave strength is higher than the preset value, the controller is made operative, and then the demodulated received data of the received signal are sent to the controller. The controller operates when the preset value is set in the transmitter/receiver, and analyzes the received data when the received wave strength has exceeded the preset value.

摘要： A solid state image pickup apparatus capable of reading a signal at a high speed while securing a wide dynamic range is provided. A signal based on a part of charges having overflown a photoelectric conversion unit (201) to a floating diffusion region (205) is quantified at an upper bit of an AD converter (206), and a signal based on charges stored in the photoelectric conversion unit (201) is quantified at a lower bit of the AD converter (206). Thereby, multi-bit data having a wide dynamic range can be taken out at a speed as high as possible without increasing the number of devices.
