WebJul 26, 2024 · The CHERI project originally targeted the MIPS processor architecture, but more recently has moved its focus to include RISC-V and Arm as well. Not only is Arm a much more significant processor architecture these days, but because Arm Ltd started out as an offshoot of Acorn Computers, it's also headquartered in Cambridge. WebCHERI is a hybrid capability-system architecture that combines new processor primitives with the commodity 64-bit RISC ISA enabling software to efﬁciently implement ﬁne-grained memory protection and a hardware-software object-capability security model.
