Capability Hardware Enhanced RISC Instructions
Capability Hardware Enhanced RISC Instructions (CHERI) is a technology designed to improve security for reduced instruction set computer (RISC) processors. CHERI aims to address the root cause of the problems caused by lack of memory safety in common implementations of programming languages such as C (programming language), C and C++, which are responsible for around 70% of security vulnerabilities in modern systems. The hardware works by giving each reference to any piece of data or system resource its own access rules. This prevents programs from accessing or changing things they should not. It also makes it hard to trick a part of a program into accessing or changing something that it should be able to access, but at a different time. The same mechanism is used to implement privilege separation, dividing processes into compartments that limit the damage that a bug (security or otherwise) can do. CHERI can be added to many different instruction set architectures including MIPS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Codasip
Codasip (Abrev., abrev. CO-Design Application-Specific Instruction-set Processor) is a Processor (computing), processor technology company enabling system-on-chip developers to differentiate their products. The company specializes in RISC-V processor technologies and offers Codasip Studio, a tool suite for processor design using the CodAL architecture description language. The company's headquarters are in Munich, Germany. Codasip has claimed that there are more than 2 billion processor cores that have been produced using their technology. History In 2014, Codasip was founded on the basis of Karel Masařík's Doctor of Philosophy, PhD work on a distinct hardware/software co-design technology, after a decade of intensive research at Brno University of Technology. In the same year, the company secured a seed funding round of $4.5M, led by Credo Ventures. In 2015, Codasip co-founded RISC-V International (initially known as RISC-V Foundation) and also launched the first commercia ...
