The present disclosure provides an integrated circuit and a computing system. The integrated circuit and a computing system includes a dynamic voltage and frequency scaling (DVFS) operation and a method of operating the integrated circuit. The integrated circuit includes a plurality of sub blocks and a dynamic voltage and frequency scaling (DVFS) controller. The DVFS controller is configured to output a workload of the plurality of sub blocks, determine a first frequency corresponding to the workload, determine a first voltage corresponding to the first frequency, and provide a second frequency among at least one frequency corresponding to the first voltage to the plurality of sub blocks.

Integrated circuit and computing system performing dynamic voltage and frequency scaling and method of operating integrated circuit

A method of operating a computing system includes receiving, by a GPU driver included in a CPU of the computing system, a plurality of commands associated with a plurality of rendering targets included in a frame buffer of the computing system, storing the plurality of commands in a command buffer included in the GPU driver, setting, by a command manager included in the GPU driver, at least one unused rendering target among the plurality of rendering targets to a delayed submission mode, and selectively deleting, by the command manager, a command associated with the at least one unused rendering target set to the delayed submission mode from the command buffer based on whether the command includes an instruction to invalidate a rendering result associated with the at least one unused rendering target.
