Fast End-to-End Performance Simulation of Accelerated Hardware-Software Stacks

The increased use of hardware acceleration has created a need for efficient simulators of the end-to-end performance of accelerated hardware-software stacks: both software and hardware developers need to evaluate the impact of their design choices on overall system performance. However, accurate full-stack simulations are extremely slow, taking hours to simulate just 1 second of real execution. As a result, development of accelerated stacks is non-interactive, and this hurts productivity.
