Dubhe-90

is the highest-performance commercial domestic RISC-V CPU Core IP that is deliverable. It adopts an 11+ stage and 5-issue pipeline, superscalar, and deep out-of-order execution, and supports standard RISC-V RV64GCBH extensions. It is optimized for the highest performance and frequency, and its SPECint2006 score achieves 9.4/GHz. Dubhe-90 is pre-integrated and verified to ease SoC integration and development with options of single-core, dual-core, or quad-core in a single cluster with memory coherency. It can be widely applied in high-performance computing scenarios and devices, such as data centers, PC, mobile devices, high-performance network communications, and machine learning.
