Image processing apparatus and method of controlling the same

摘要: Texture mapping is performed on polygons at the same speed as a polygon drafting process without texture cache, thereby preventing complexity and an increase in cost. An image memory (8) constituted double-buffer structure, address line, data line control are individually connected to each buffer. One of two buffers used for data, other drawing result. The one-dimensional, size thereof less than maximum value column address. buffer imaginary double with buffers, one being reading out from SAM port, writing produced polygons. Read/write switching effected vertical flyback period. In read-out buffer, just after row-directional read-out, associated row cleared by flash write function multiport DRAM horizontal period, next output. synchronism this, refreshed.
