11.7. Experimental Results

For the 3D rendering QoS application introduced in the previous section, we applied our complete design flow, from modeling to scenario selection to scheduling, and then compared the result with a few reference cases, by using our simulation environment.

11.7.1. Gray-Box Model

In the QoS kernel, for each visible object on the scene, a separate TF will be triggered, in which the number of triangles is adjusted to the number specified by the QoS algorithm. The gray-box model of that TF is shown in Figure 11-8, in which all the internal TNs are numbered as well. Table 11-1 gives the profiled execution time and energy consumption of each TN on a 2.4-V StrongARM processor.
