We describe novel techniques used for efficient simulation of memory in SimICS, an instruction level simulator developed at SICS. The design has focused on efficiently supporting the simulation of multiprocess, analyzing complex memory hierarchies and running large binaries with a mixture of system-level and user-level code. A software caching mechanism (the Simulator Translation Cache, STC) improves the performance of interpreted memory operations by reducing the number of calls to complex memory simulation code. Major data structures are allocated lazily to reduce the size of the simulator process. A well-defined internal interface to generic memory simulation simplifies user extensions. Leveraging on a flexible interpreter based on threaded code allows runtime selection of statistics gathering, memory profiling, and cache simulation with low overhead. The result is a memory simulation scheme that supports a range of features for use in computer architecture research, program profiling, and debugging.
