    Abstract: A radio timepiece, including: a satellite radio wave receiver; a ground wave receiver; a memory; and a controller, wherein the controller performs area determination operation of determining whether a current position is located within a geographical range where the ground wave receiver is capable of acquiring notice information regarding implementation/non-implementation of the leap second adjustment, when the controller determines that the current position is located within the geographical range, the controller controls the ground wave receiver to acquire the notice information, the controller determines, with the notice information, whether the leap second adjustment is scheduled to be implemented at an implementation candidate timing of the leap second adjustment, and when the controller determines that the leap second adjustment is scheduled to be implemented, the controller changes the leap second correction information at or after the implementation candidate timing.

    Abstract: A satellite radiowave receiving device includes a receiver and a processor. The receiver acquires and receives radiowaves from a positioning satellite. The processor performing a positioning operation based on the radiowaves received by the receiver to obtain a current position of the satellite radiowave receiving device. The processor causes the receiver to stop an acquiring operation of radiowaves from a new positioning satellite under a predetermined condition while radiowaves are being acquired from a required number of positioning satellite for the positioning operation. If an error range of the obtained current position no longer satisfies a predetermined accuracy standard during a stop of the acquiring operation, the processor causes the receiver to resume the acquiring operation.

    IPC: G06F3/06

    Abstract: A control device, including: a first processor; a second processor which has a higher performance than the first processor; and a storage in which data is stored so as to be readable and writable by the second processor, wherein a part of the storage is usable as a common storage area which is readable and writable by the first processor and the second processor, in reading operation, the second processor reads first data from out of the common storage area in the storage and writes the first data to the common storage area, and the first processor reads the first data from the common storage area, and in writing operation, the first processor writes second data to the common storage area, and the second processor stores the second data out of the common storage area in the storage.

    Abstract: An electronic device includes: a memory configured to a program; and one or more processors configured to execute the program stored in the memory. The one or more processors are connected to a first circuit and a second circuit, the first circuit being configured to execute a first operation cyclically and output an interrupt signal corresponding to the first operation, the second circuit being configured to execute a second operation in response to an operation instruction. In response to receiving the interrupt signal, the one or more processors output the operation instruction to the second circuit such that the second operation is not executed in a period in which the first operation affects the second operation.
