Since 1999, OpenCores is the most prominent online community for the development of gateware IP (Intellectual Properties) Cores. It is the place where such cores are shared and promoted in the spirit of Free and Open Source collaboration. ...
1Introduction The free and open RISC-V Instruction Set Architecture (ISA) has attracted an active community building processor cores and ecosystems, which makes it competitive to established processor designs. There is a strong growth forecast for the number of RISC-V cores in industrial-, consumer...
2.2. Instruction set extension Compared with simply connecting an encryption module to a processor unit, integrating the encryption module into the processor unit has unique competitive advantages. In this manner, it is possible to share hardware resources such as decoders and register stacks, optimizi...
