Presentation
GPU Power Tracking and Optimization Using Emulation
DescriptionThis presentation is about tracking dynamic power using real-world emulation use-cases/workloads at GPU IP level rather than bottoms up projections based on unit level tests. This enables exploration of biases in real-world data-patterns and design scenarios while also being able to track relative power trends and quantify the impact of RTL, physical design and software changes on IP power throughout the course of project execution. We use SAIF from emulation for average power estimation flow and FSDB for power optimization flow. Our approach resulted in the discovery of significant power optimization opportunity at the GFX IP level. Furthermore, it helped us successfully identify regressions in power between successive versions of the GFX IP using relative RTL trend tracking technique. Overall, this helps with left shifting the GFX IP level power analysis and optimization effort and avoid late RTL surprises which directly translates into better perf-per-watt for the product.
