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 oscillator1that generates a periodical synchronizing signal and a PLL2,a memory that stores the data, at least one CPU13that conducts a computing process using the data stored in the memory, at least one MAC14that controls an access from the CPU13to the memory, and at least one NB12that generates the system clock having a frequency that is an integral multiple of the synchronizing signal, and controls the CPU13and the MAC14based on the operation by the system clock.
