PURPOSE:To lighten the load on a CPU without reducing the computing capability of the CPU itself on a main bus by incorporating a dedicated arithmetic part for performing geometrical arithmetic in the CPU as hardware. CONSTITUTION:In an image processing system which uses the CPU 12, the CPU 12, a main memory 13, and a raster processor 14 are connected to a main bus 11. The CPU 12 is provided with a matrix arithmetic part 100 as a dedicated arithmetic part for the function part of a geometric processor. A CPU part 22 is connected to this arithmetic part 100 through an internal bus 21 and for a process for converting coordinates of polygon data, a function for the multiplication of a matrix of nXm=3X3 and a vector of degree m=3, a function for the addition and subtraction of a vector of degree n=3 and a vector of degree n=3, a function for the term-classified multiplication of a vector of degree n=3 and a vector of degree n=3, and a function for the multiplication of a vector of degree n=3 and a scalar value, and a function for division between scalar values are exclusively executed. |
