3D GRAPHIC CONTROLLER

摘要

PURPOSE: A three-dimensional graphic controller is provided to improve an operation performance by embodying a cache memory so that stored MIP maps corresponds to two-dimensional texture images. CONSTITUTION: The first cache memory(No.1) stores two-dimensional texture image transmitted from each first MIP map(MIPmap No.1) among a plurality of MIP map sets(MIPmap SET 1-MIPmap SET n). The second cache memory(No.1) stores two-dimensional texture image transmitted from each second MIP map(MIPmap No.2) among a plurality of MIP map sets(MIPmap SET 1¯MIPmap SET n). The third cache memory(No.1) stores two-dimensional texture image transmitted from each first MIP map(MIPmap No.3) among a plurality of MIP map sets(MIPmap SET 1-MIPmap SET n). The fourth cache memory(No.1) stores two-dimensional texture image transmitted from each first MIP map(MIPmap No.4) among a plurality of MIP map sets(MIPmap SET 1-MIPmap SET n).
