Patent ID: 7493508

Claim:
An information processing apparatus operating in synchronism with a synchronizing clock signal of a predetermined frequency, said information processing apparatus comprising: clock outputting means for varying said frequency of said synchronizing clock signal in order to output said synchronizing clock signal at the varied frequency; holding means for inputting and holding data when said clock outputting means outputs a first clock signal pulse, said holding means further outputting said data held therein when said clock outputting means outputs a second clock signal pulse following said first clock signal pulse; selection command generating means for generating a selection command specifying whether or not to transfer said data by bypassing said holding means in accordance with the frequency of said synchronizing clock signal output by said synchronizing clock outputting means; and bypassing means for outputting said data by bypassing said holding means if said selection command generated by said selection command generating means specifies that said data be transferred by bypassing said holding means, said bypassing means further outputting said data output by said holding means if said selection command specifies that said data be transferred without bypassing said holding means, wherein when the holding means is bypassed, said synchronizing clock signal supplied to the holding means is cut off.
