Recent extensions to the SimpleScalar tool suite

Over the past eight years, the SimpleScalar Tool suite has become the most widely used set of simulation tools in the computer architecture research community. The authors have recently completed an NSF-funded project to extend and improve the SimpleScalar tools. In this paper, we describe the extensions and improvements to the tools, which include the capability to simulate more instruction sets, graphical support for performance viewing, and more simulators that model different types of machines, including embedded systems, ISA-specific systems, systems with operating system, and multiprocessing systems.
