Abstract:
A method of synchronizing first clocks and second clocks for transferring data from a first circuit operated at said first clocks through a storing means being accessible independently to its input and output to a second circuit operated by said second clocks comprising the steps of;storing said data fed by said first circuit; detecting whether said data stored in said storing means is effective data; renewing, if a decision is positive, an access pointer of said storing means in response to each of said first clocks or each of said second clocks; re-initializing, if a decision is negative, said access pointer of said storing means in response to each of said first clocks or each of said second clocks; and outputting data inputted in synchronization with said first clocks in synchronization with said second clocks by accessing said storing means using said access pointer.
