 This library provide the infrastructure to build RISC-V ISS. Currently part of the library are the following implementations adhering to version 2.2 of the 'The RISC-V Instruction Set Manual Volume I: User-Level ISA':
 
-* RV32IMAC
-* RV32GC
-* RC64I
-* RV64GC
+* RV32I 	(TGF-B)
+* RV32MIC	(TGF-C)
 
-All pass the respective compliance tests. Along with those ISA implementations there is a wrapper implementing the M/S/U modes inlcuding virtual memory management and CSRs as of privileged spec 1.10. The main.cpp in src allows to build a standalone ISS when integrated into a top-level project. For further information please have a look at [https://git.minres.com/VP/RISCV-VP](https://git.minres.com/VP/RISCV-VP).

 Last but not least an SystemC wrapper is provided which allows easy integration into SystemC based virtual platforms.
