APPARATUS AND METHOD TO IMPROVE SWITCHABLE GRAPHICS SYSTEM PERFORMANCE AND ENERGY CONSUMPTION BASED APPLICATIONS AND REAL-TIME SYSTEM POWER/THERMAL BUDGETS

Abstract:

A switchable graphics management scheme, which uses performance/watt information of both the iGPU/dGPU along with system real-time resources like SoC (system-on-chip) thermal, system power budgets to decide on the right GPU for rendering tasks. The scheme uses this threshold power point information along with system resources to determine the optimized GPU for tasks rendering for all applications and use cases. As such, the scheme of adapts to each system design based on capabilities of that specific system.
