IMAGE ROTATION PROCESSING METHOD AND PROCESSING DEVICE FOR RELEVANT METHOD

摘要: PURPOSE:To enable a high-speed processing in system equipped with an image memory such as low-speed DRAM rotation to rotate rectangular at arbitrary angle corresponding parameter. CONSTITUTION:An inside 7 is provided the storage capacity of 2(words)X2(bits)/(word), and transfer source divided into line (word)X(bits)/(word), read for unit word each line, drawn onto by using DDA transferred destination 5 one block. Since hierarchized number times performing access decreased, acceleration enabled.
