DATA PROCESSING METHOD, DATA PROCESSING DEVICE, AND PROGRAM FOR EXECUTING FONT PROCESSING BY EFFICIENTLY USING MULTIPLE CORES OF PROCESSOR

摘要

To efficiently use a plurality of cores in font rasterization processing.SOLUTION: A data processing device includes a CPU having N cores, a memory, and a storage part for storing a control program. The control program causes the data processing device to execute steps including: a search step of searching a new character which is a character whose raster data is not stored in the memory among a plurality of characters specified by character data included in print data to count a count of the searched new characters; a thread generation step of generating M threads, where M is a count determined on the basis of the count of the counted new characters among the N cores; a raster data generation step of distributing and allocating the plurality of characters to the M threads to generate raster data for the new characters by using any one of the N cores for each of the M threads; and a rendering step of rendering the plurality of characters by using the raster data corresponding to the character data.SELECTED DRAWING: Figure 1
