PROBLEM TO BE SOLVED: To provide a graphics system capable of increasing the speed of data input and arithmetic processing without enlarging a system scale and easily coping with a shader. SOLUTION: The graphics system comprises an SIMD type arithmetic unit 2 having local memories FLM0-FLM3 holding data required for geometric operation, and computing elements FPU0-FPU3 carrying out geometric operation using data held in the FLM0-FLM3; and an input processing section 3 comprising an address generator 18 computing a read-out address of data, a type converter 12 converting the type of input data, and an initial value register 14 setting an initial value to the FLM when the number of input data subjected to parallel operation of the FPU0-FPU3 is less than the number of FLMs. COPYRIGHT: (C)2007,JPO&INPIT |
