Up to 256 cores, Saifang Technology releases new RISC-V many-core subsystem IP platform

According to news from this site on November 24, Saifang Technology announced its independently developed on-chip consistent interconnection IP - StarLink-700 (StarLink-700), and launched the StarLink-700 and Fang... RISC-V many-core subsystem IP platform of Tianshu-90 (Dubhe-90).

StarLink-700 is an Interconnect Fabric IP developed by Sai Fang Technology that supports cache consistency. It is known as It is the first Mesh architecture interconnection bus IP in China. StarLink-700 supports a maximum of 144 nodes, a single node can connect 2-5 devices, and the number of connectable CPUs is up to 256; it supports IO device Cache consistency, request concurrency and QoS, supports Snoop Filter, and supports CHI protocol.

Dubhe-90 is the flagship product of Sai Fang Technology's Dubhe Max Performance series, focusing on ultimate performance. It was released in August this year and adopts an 11-stage pipeline, five launches, superscalar, and deep out-of-order Implementing other designs, the performance is said to be comparable to ARM Cortex-A76, SPECint2006 9.4/GHz. Dubhe-90’s customers mainly come from application fields such as PC, network communications, machine learning, and data centers.

Based on Dubhe-90 and StarLink-700, Sai Fang Technology has built a RISC-V many-core subsystem IP platform. The platform also includes: RISC-V Debug Module debugging interface, RISC- V Interrupt controller (PLIC, CLINT), power management, security, virtualization, IO Coherency and memory subsystem. The RISC-V many-core subsystem IP platform can be widely used in servers, DPUs, computing storage, network communications, AI and other fields.

According to our previous reports, Sai Fang Technology has launched four products this year, including two RISC-V CPU Core IPs, namely Fang Tianshu-90 (Dubhe-90), which focuses on extreme performance. ) and the Fang Tianshu-80 (Dubhe-80), which focuses on high energy efficiency, there is also an on-chip consistent interconnect IP - the Fang Starlink-500 (StarLink-500), and a RISC-V multi-core subsystem IP Platform
