Taxim: A Toolchain for Automated and Configurable Simulation for   Embedded Multiprocessor Design
  Multicore embedded systems have been constantly researched to improve the efficiency by changing certain metrics, such as processor, memory, cache hierarchies and their cache configurations. Using Multi2Sim and McPAT simulators in combination allows the user to design various multiprocessing architectures and estimate performance, power, area and timing metrics. However, the design time required to simulate these systems is daunting and prone to human error. In this paper, we introduce Taxim, a toolchain that can automatically create requested multicore on-chip topologies along with minimizing the simulation time due to repetitive tasks between architectural power, energy and timing simulations. Taxim's decision-tree-based topology synthesis tool creates processor configuration files that can be highly erroneous when generated manually. The toolchain also automates the steps from design entry to output report extraction by running automation scripts, and listing the results. Our experiments show that multiprocessing architectures with 32 cores and irregular cache hierarchies are more than 1k lines of code in Multi2Sim's processor configuration format and Taxim can create such a file in less than 10 milliseconds.
