Dubhe Series

As a 64-bit high performance CPU Core IP based on RISC-V, Dubhe offers the most complete instruction sets so far, including RV64GC, B (Bit Manipulation), N (User-Level Interrupts), and instruction sets needed for high-performance computing, including V (Vector 1.0)  and H (Hypervisor). The working frequency of Dubhe can reach 2GHz@TSMC 12nm, with SPECint2006 of 8.9/GHz, Dhrystone of 6.6 DMIPS/MHz and CoreMark of 7.6/MHz. Dubhe is a super scaler design with deep out of order execution, and is highly optimized for performance.
