WebThe CHERI architecture allows pointers to be implemented as capabilities (rather than integer virtual addresses) in a manner that is compatible with, and strengthens, the semantics of the C language. In addition to the spatial protections offered by conventional fat pointers, CHERI capabilities offer strong integrity, enforced provenance validity, and … WebCHERI's ISA extensions and features are considered extremely experimental and are an active target of continuing research. Documentation for these ISA extensions may be found in the CHERI Architecture Document. The primary BERI release targets the DE4 FPGA board from Terasic [1] which contains an Altera Stratix 4 GX230 FPGA.
