Abstract
To provide a system clock distributing apparatus and a system clock distributing method for reducing a skew of a system clock and a synchronizing signal at low cost. The system clock distributing apparatus for matching the timing of data by using the synchronizing signal includes an oscillatorthat generates a periodical synchronizing signal and a PLLa memory that stores the data, at least one CPUthat conducts a computing process using the data stored in the memory, at least one MACthat controls an access from the CPUto the memory, and at least one NBthat generates the system clock having a frequency that is an integral multiple of the synchronizing signal, and controls the CPUand the MACbased on the operation by the system clock.
