The Lcode produced is optimized for ILP, but not for a specific machine. This code is then passed to the Elcor compiler, along with a machine description (MDES) that specifies the target machine. Elcor compiles the code for the target machine, producing another IR called rebel. Simu consumes the rebel code, executes the code, and gathers execution statistics.Intermediate RepresentationsC CodeFront end (IMPACT)L CodeP Code L CodeBack end (Elcor)Elcor IR RebelMDESRebelUses and StrengthsGeared toward compiler and architecture research. Used for designing, implementing, and testing new optimizations, as well as the evaluation of various architectural innovations. Widely used for teaching and education purposes at several universities worldwide.Highly parameterizable.Can target a wide range of architectures that embody embedded processors, high-end VLIW processors, and multi-clustered architectures.Facilitates the exploration of the architecture design space.Well suited for the automatic synthesis of programmable application specific architectures.Allows for customization of all aspects of an architecture, including the datapath, control path, instruction set, interconnect, and instruction/data memory subsystems. Easy construction and insertion of new compilation modules into the compiler. Trimaran Graphical User Interface (GUI) makes the configuration and use of the system easy.Benchmark ProgramsAvailable at www.trimaran.org/benchmarks.shtmlSPECINT 2KSPECINT 95SPECINT 92Mediabench•Olden•MiBench•NetBench•EncryptionLimitationsCentered around HPL-PD so it supports limited architectures.Not really a limitation as it was developed for exploring these architectures.Planned EnhancementsSolaris PortLinux portAdd measurements for cache
