PURPOSE:To provide a cache memory only to the CPU which refers to graphic data, but not to the CPU which receives a request from a client and generates, releases and destroys graphic data, for eliminating the need for a cache flash for guaranteeing the identity of conventional data and for speeding up the processing of graphic data in a high speed server which processes graphic data at a high speed through the use of plural CPUs. CONSTITUTION:CPU 1 generating, releasing and destorying graphic data on a shared memory 4 in accordance with the request and CPU 2 writing graphic data on the shared memory 4 into the cache memory 3 provided for a space with the shared memory 4, writing it into FIFO 401 in a state where graphic data is only referred to and it is not rewritten into the shared memory 4 and requesting a plotting processing in accordance with the reception of a plotting instruction issued from the CPU 2 are provided. Then, a distribution processing is executed. |
