摘要
The invention concerns a method for controlling a graphic processing unit, GPU, (17) in a control unit (1), in particular of a vehicle, the control unit comprising at least one central processing unit, CPU, the at least one CPU (3) having access to at least one memory (5); the GPU (17) being connected to and controlled by the at least one CPU (3), wherein the GPU (17) is adapted to provide frames to at least one display (13) having a predetermined output display frame rate, the method comprising: receiving (1000), by a GPU server (32) running on the CPU (3), a low priority graphical output from a first application (42), providing, by the GPU server (32), the low priority graphical output to the GPU (17), starting (1010), by the GPU (17), the rendering of the low priority graphical output, receiving (1020), by the GPU server (32), a time critical graphical output from a second application (44); determining a first point in time (t3) before the next frame (n+2) to be provided to the at least one display (13) based on second point in time (t4), when the next frame (n+2) is to be provided to the at least one display (13), and the maximal time needed to display the time critical graphical output on the at least one display (13) using the GPU (17); and forcing (1050), at the determined first point in time (t3), by the GPU server (32), the GPU (17) to render the time critical graphical output, if at the determined first point in time the GPU (17) still renders the low priority graphical output
