GRAPHIC DATA PROCESSING SYSTEM IN GRAPHIC PROCESSING SYSTEM

摘要

PURPOSE: To improve a data transfer efficiency to an FIFO connecting to a graphic processing processor in the graphic processing system having a graphic processing processor in addition to a CPU. ;CONSTITUTION: The system has a threshold register 12 storing a threshold used to discriminate the propriety of transfer of data to an FIFO 11, a monitor section 13 monitoring an amount of data stored in the FIFO, comparing the amount with a threshold stored in the threshold register and providing an output of a comparison result, a status information register 14 storing status information denoting whether the amount of data stored in the FIFO is the threshold or over or less than it, and a status information revision section 15 revising the status information on the basis of the comparison result from the monitor section.;COPYRIGHT: (C)1996,JPO
