Saifang Technology releases the world's first RISC-V large and small core processor subsystem, with performance comparable to ARM A76 / A75

According to news from this site on August 17, Sai Fang Technology today released two new independently developed RISC-V processor core products: Fang Tianshu-90 (Dubhe-90) and Fang Tianshu -80(Dubhe-80).

According to the introduction, Dubhe-90 is the flagship product of Dubhe Max Performance series, focusing on providing ultimate performance; while Dubhe-80 is the first product of Dubhe Efficiency Performance series, focusing on high energy efficiency ratio. These two products are also widely known as the large and small cores of the CPU

At the same time, based on Dubhe-90, Dubhe-80 and Xifang Technology’s on-chip consistent interconnection IP - StarLink-500 (StarLink -500), Saifang Technology has released the first domestic high-performance RISC-V multi-core subsystem IP platform, claiming to be the world's first RISC-V large and small core processor subsystem solution, filling the gap between RISC- There is a gap in the corresponding market in the V field.

Sai Fang Technology name, 昉·天树-90 "big core" performance is comparable to ARM Cortex-A76, SPECint2006 9.4/GHz. Customers mainly come from high-end application fields such as PC, high-performance network communications, machine learning, and data centers.

Compared with 昉・天顺-90, 昉・天顺-90 The Hub-80 is claimed to have a 50% improvement in energy efficiency with a performance difference of only 20%, meeting the application needs of mobile, desktop, industrial control, artificial intelligence, automotive and other scenarios.

昉・天树-80 adopts a 9-stage pipeline, three-launch, out-of-order execution design, SPECint2006 8.0/GHz, claims to have performance exceeding ARM Cortex-A75, and supports the most complete RISC-V to date Instruction set , including RV64GC, bit operation extension B (Bitmanip 1.0), vector extension V (Vector 1.0) and virtualization extension H (Hypervisor 1.0), etc.

Based on Dubhe-90, Dubhe-80 and StarLink-500, Saifang Technology releases the first domestic high-performance RISC-V multi-core subsystem IP platform solution, supports the consistent collaborative work of 8 cores, and can be widely used in PCs, laptops, mobile devices, thin Main control chip design for clients, NAS, industrial computers and various industry terminals. A search on this site found that Sai Fang Technology's RISC-V processor - Fang Jinghong-8100 (JH-8100) adopts this design.
