Abstract
A data processing system includes a processor for writing data processed based on a clock signal in a buffer for storing and outputting written data, and the processor changes a frequency of the clock signal supplied to the processor in accordance with an amount of data stored in the buffer.
Claims6
A data processing system comprising:
- a clock control unit supplying a clock signal;
- a processor coupled to said clock control unit to output write data in accordance with said clock signal, an amount of said write data being responsive to a frequency of said clock signal;
- and
- a buffer coupled to said processor to receive said write data as a new entry of stored data therein and output a part of said stored data, said entry of said stored data increasing in response to said write data and decreasing in response to said part,
- wherein said processor controls said frequency of said clock signal in response to an amount of said entry in said buffer.
2 more elements
A combination comprising:
- a circuit outputting a data;
- and
- a buffer receiving said data to store said data;
- wherein said circuit controls an amount of said data in response to a remaining capacity of said buffer.
