Abstract
A method and device for synchronizing the time between at least two integrated circuits (201, 202), which receive the same pulse signal. In the integrated circuits (201, 202) a counter (204, 206) is used to count the number of pulses in the received pulse signal to synchronize the common time between said integrated circuits.
Claims17
A method for establishing common time information between at least two integrated circuits, where at least one integrated circuit receives a clock signal, wherein in each of said at least two integrated circuits:
- a number of pulses of said clock signal is calculated, and
- the common time information between said at least two integrated circuits is established on the basis of counting the number of said pulses.
A method according to claim. 1, wherein said clock signal is generated outside said integrated circuits.
An integrated circuit for establishing common time information between said integrated circuit and at least one other integrated circuit, comprising receiving means for receiving a clock signal, wherein said integrated circuit further comprises;
- counting means for counting a number of pulses of said clock signal, and
- establishment means for establishing the common time information between said integrated circuit and the at least one other integrated circuit on the basis of counting the number of said pulses.
An electronic device comprising at least two integrated circuits, said at least two integrated circuits comprising receiving means for receiving a common clock signal from a clock signal source, wherein the device further comprises in each of said at least two integrated circuits:
- counting means for counting a number of pulses of said common clock signal, and
- establishment means for establishing common time information between said at least two integrated circuits on the basis of counting the number of said pulses.
