  • Publication number: 20070018708
    Abstract: A method of and an apparatus for determining an optimal delay time and a computer-readable storage medium storing an optimal delay time determining program. By determining an optimal delay time between data packet transmissions from a master to a slave through a serial data line, speed reduction and overload of a master/slave system is preventable. A data packet is transmitted from the master to the slave through the serial data line and the master judges whether the transmitted data packet is received within a predetermined delay time based on an acknowledge signal received from the slave. If the acknowledge signal is not received by the master within the predetermined delay time, the master increases the delay time by an increment and re-transmits the data packet. The incrementing, transmitting and judging are repeated until an optimal delay time is determined.
