RV32I - Base Integer, 32-bit

An extensible and configurable RISC-V based Virtual Prototype (VP) implemented in SystemC TLM. The feature set includes support for the RV32GC and RV64GC ISA, privilege levels (M,S,U), virtual memory, SW debug via Eclipse, a HiFive1 configuration and several operating systems including Linux. At UB the RISC-V VP serves as platform for several different research directions (visit https://agra.informatik.uni-bremen.de/projects/risc-v/ for further information and the most recent updates).

ETISS is a C++ ISS (Instruction Set Simulator), which is designed to simulate instructions for a target core on a host computer. It translates binary instructions into C code and appends translated code into a block, which will be compiled and executed at runtime. As aforementioned, it is Extendable, thus it supports myriad level of customization by adopting the technique of plug-ins. ETISS supports varied Instruction Set Architectures (ISAs) according to user needs (see architecture models in ArchImpl/).

CompCert is a formally verified optimizing C compiler. It accepts most of the ISO-C 99 language, with some minor exceptions and a few useful extensions. Its intended use is the compilation of life-critical and mission-critical software written in C and meeting high levels of assurance.
