ENCODER, METHOD THEREOF, AND GRAPHIC PROCESSING APPARATUS

摘要

An encoder capable of making a processing time shorter, wherein the position of a first "1" bit seen from the MSB of the digital data 160 is output as a first bit encoded data and the second "1" bit is output as the second bit encoded data. A predetermined calculation is performed in parallel on the upper 8 bits of the digital data in the valid detector, the priority encoder, and the first valid bit mask unit, while a predetermined calculation is performed in parallel on the lower 8 bits in the priority encoder and the first valid bit mask unit.
