<p>PROBLEM TO BE SOLVED: To provide an arithmetic processor capable of processing data with high data quantity such as picture data at high speed by small scale and at a low manufacturing cost. SOLUTION: A data buffer memory 15 is provided with a first storage area to store stream data and a second storage area to store the picture data, and inputs and outputs the stream data between the first storage area and a CPU 10 in a FIFO system. The sizes of the first and second storage areas can be changed based on a value of a control register. Data except the picture data is transferred between the CPU 10 and an external memory 14 through a secondary cache memory 13 and a data cache memory 12.</p> |
