Sai Fang launches 64-bit ultra-low power consumption out-of-order RISC-V CPU core IP Fang Tianshu-70

According to news from this website on August 16, domestic RISC-V ecological enterprise Saifang Technology yesterday announced the launch of a new 64-bit RISC-V processor core product Tianshu-70 (Note from this website: Dubhe-70), which is suitable for Segments that require both high performance and extremely low power consumption.

昉・The Tianshu-70 core adopts a 9+ stage pipeline, three-issue, superscalar, out-of-order execution design, supports the RV64GCBH instruction set, and scored 7.2 points per GHz frequency in the SPECint2006 benchmark test, with performance benchmarked against Arm Cortex- A72/A510.

Sai Fang has previously launched the Fang Tianshu-90 (Dubhe-90), which "focuses on ultimate performance", and the Fang Tianshu-80 (Dubhe-80), which "focuses on high energy efficiency ratio". This time Fang・The release of Tianshu-70 further enriches Xifang's RISC-V CPU IP product line.

Saifang stated that compared with Arm Cortex-A55, the performance of Fang·Tianshu-70 is 80% higher, the energy efficiency ratio is 32% higher, and the area-effectiveness ratio is 90% higher; and compared with its own Fang·Tianshu-70 80, the energy efficiency ratio of Fang·Tianshu-70 has increased by 21%, and the area-effectiveness ratio has also increased by 5%.

The above is the detailed content of Sai Fang launches 64-bit ultra-low power consumption out-of-order RISC-V CPU core IP Fang Tianshu-70. For more information, please follow other related articles on the PHP Chinese website!
