Patent ID: 8624905

Claim:
A portable terminal, comprising: a controller; a first graphical processing core configured to process data; a second graphical processing core, which is faster than the first graphical processing core, configured to process the data, wherein the first and second graphical processing cores are integrated into a single chipset, wherein the portable terminal is configured to be operated in a standby state or an operating state, and wherein the first and second graphical processing cores are configured to be individually enabled or disabled based on a workload in the operating state; and a storage unit configured to store multimedia data, wherein the portable terminal is configured to play back the multimedia data stored in the storage unit, wherein the portable terminal is configured for Internet access, wherein the controller is configured to: calculate an average speed for processing an executable application program, assign image data generated by the executable application program to the first graphical processing core if the average speed is lower than a first reference value, and assign the image data generated by the executable application program to the second graphical processing core if the average speed is above the first reference value; and wherein the controller is further configured to: calculate an amount of the image data generated by the executable application program, assign the image data to the first graphical processing core if the amount of image data is lower than a second reference value, and assign the image data to the second graphical processing core if the amount of image data is above the second reference value.
