Abstract
With traditional boundaries between embedded and general-purpose computing blurring, both domains increasingly deal with complex, heterogeneous, software-intensive yet tightly constrained systems. This creates new challenges for modeling, synthesis and component design at the intersection of applications and architectures. For modeling of inherently dynamic behavior, simulations continue to play an important role. We first present an abstract, host-compiled modeling approach that provides a fast and accurate alternative to traditional solutions. By navigating tradeoffs in coarse-grain executions, full-system simulations in close to real time with more than 90% accuracy become possible. Models then provide the basis for automated design space exploration as part of a system compiler that can automatically synthesize parallel application models onto optimized hardware/software platforms. Finally, we will discuss results on co-design of novel domain-specific components for future heterogeneous platforms. We specifically explore fundamental tradeoffs between flexibility and specialization, and between error acceptance and energy in the design of high-performance yet low-power processors for linear algebra and signal processing applications.
