Dubhe Series
StarFive Dubhe is the first commercial RISC-V CPU IP to support a rich set of RISC-V extensions, including latest B (bit-manipulation), V (vector) and H (hypervisor) extensions, enabling more edge cloud and high-performance computing applications running on RISC-V.
Dubhe is a superior high-performance 12-stage pipeline out-of-order RISC-V CPU core which supports standard RISC-V RV64GCBVHN extensions and targets for applications which require high-performance computation capability. It is highly scalable, optimized for highest performance and frequency design, bringing the total 31 SPECint2k6 supreme performance. Dubhe is pre-integrated and verified into the core complex to ease SoC development efforts and provides options of single core, dual-core, or quad-core in a single cluster with memory coherency.
