System clock distributing apparatus and system clock distributing method

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 oscillator that generates a periodical synchronizing signal and a PLL a memory that stores the data, at least one CPU that conducts a computing process using the data stored in the memory, at least one MAC that controls an access from the CPU to the memory, and at least one NB that generates the system clock having a frequency that is an integral multiple of the synchronizing signal, and controls the CPU and the MAC based on the operation by the system clock.
