Texture pattern memory circuit for providing plural texel data in response to a single access operation

摘要

This texture pattern memory circuit is composed of a multi-texture pattern memory, a writing device and a texel selector. The multi-texture pattern memory includes an adder, a subtracter, selectors, 1st to 4th address converting devices, and 1st to 4th memory modules. The texel selector selects only the necessary data from the texel data outputted from the multi-texture pattern memory.
