Alibaba has unveiled its RISC-V RV64GCV main that will be used for its Xuantie 910 processor aimed at cloud and edge servers.

The e-commerce large has produced a single of the industry’s very first 64-little bit RISC-V main and system-on-chip (SoC) designed for superior-functionality applications.  

The Alibaba Xuantie 910 SoC packs up to sixteen RV64GCV cores structured in 4 quad-main clusters that operate at two.0GHz ~ two.50GHz as perfectly as 4 AI-optimized vector computing engines (a single per cluster). The processor will be used largely by Alibaba alone to power its AI and edge servers, but could also be used for ADAS and industrial applications.

Large-functionality RISC-V

The RV64GCV main attributes a 12-stage out-of-get pipeline that can fetch and concern eight directions per cycle and decode three directions per cycle. Every single main is geared up with up to 128KB L1 cache (32/64KB for directions, 32/64KB for details) and all cores share up to 8MB L2 cache.

The main supports Alibaba’s proprietary RISC-V Turbo extensions that permit quicker little bit operations, memory access, multi-main synchronization, memory administration, and cache advancements. The corporation statements that, dependent on the workload, its extensions supply up to twenty{36a394957233d72e39ae9c6059652940c987f134ee85c6741bc5f1e7246491e6} functionality advancements.

Alibaba’s RV64GCV is a single of the very first industrial cores to totally support the RISC-V .seven.1 vector extensions and FP16/32/64 and INT8/sixteen/32/64 formats.

The vector engine attributes two 128-little bit ALUs that supply up to three hundred FP16 or up to one hundred fifty FP32 GFLOPS per cluster at two.50GHz. Consequently, the complete Xuantie 910 chip can offer up to 1200 FP16 or 600 FP32 GFLOPS of compute horsepower.

The developer states that, primarily based on its experiments and emulations, its RV64GCV main gives functionality similar to that of Arm’s Cortex-A73, launched in 2016 and used for cellular SoCs as HiSilicon’s Kirin 960/970, Qualcomm’s Snapdragon 835, and MediaTek’s Helio X30.  

The RISC-V is an open-normal instruction set architecture that has been used largely for microcontrollers and processors for essential applications. In the meantime, a variety of organizations, which includes Alibaba, are performing on superior-functionality RISC-V cores for demanding applications.  

Alibaba plans to receive the remaining XuanTie 910 chip implemented making use of TSMC’s 12nm FinFET technological innovation from time to time in September and if this SoC fulfills all prerequisites, expect mass production to start off soon. 

In addition, Alibaba is performing on scaled-down processors primarily based on its RISC-V cores.
