    摘要： In order to reduce degradation of the processing performance of the data processor due to use of a part of the main memory as a display frame buffer, when an access request to the memory 200 is generated from the CPU 310, the memory controller 400 holds it once, requests the display controller 560 to stop the access to the memory 200 which is in execution, when data to the access executed already is transferred from the memory 200, holds it, and transfers the access request from the CPU bus 310 which is held by the memory 200. When the access from the CPU bus 310 ends, the memory controller 400 restarts the access stopped in the display controller 560 and passes the held data to the display controller 560.

    摘要： A data processing apparatus includes physical registers larger in number than logical registers specified by a register specification field of an instruction executed by the apparatus. The physical registers are classified into a plurality of banks. In response to a particular instruction, an execution control section supplies a register address converter with bank information to select a bank of the physical register. The converter stores the bank information in a bank register. Receiving logical register address information specified by the register specification field of the instruction, the address converter adds the bank information set to the bank register to at least a portion of the logical register address information, thereby producing a physical register address which can specify any one of the physical registers.

    摘要： In a data processor and a shading apparatus used in the data processor, the data processor selects an address based on the information of a memory or a translation look-aside buffer. Therefore, even when the same data are accessed, a different address at high speed is adopted according to the hardware, object to be processed, processing, etc. A plurality of geometric vectors are given as the parameters for the vertexes of a picture, the vectors are interpolated in the picture, and the luminance of each small area in the figure is calculated using the vectors generated by the interpolation. Therefore, a spotlight or highlight can be expressed with high accuracy and at high speed even when the amount of the hardware and the extent of the picture are small.
