Alibaba unveiled XuanTie 910 16-core RISC-V Processor last year with few details except it targetted high-performance 5G, AI, and autonomous driving applications. The company has now provided more details about Alibaba XuanTie 910 (aka XT910) processor during the virtual Hot Chips 2020 conference, and he notably compared the RV64GCV core found in the processor to Arm Cortex-A73 core. Alibaba XT910 main features and specifications: CPU – Up to 16x 64-bit RISC-V (RV64GCV) cores with RISC-V Vector extension and custom Turbo extension in four clusters of four cores; 12-stage out of order; Coremark: 7.1 per MHz Cache – 32KB or 64KB I/D cache per core, up to 8MB L2 cache per cluster FP16-FP64 floating-point unit Vector Computing Unit (aka Vector Engine) for AI acceleration Memory Management – Sv39 MMU + 8/16 PMP Interrupt Controller – Clint + PLIC Process – Final: 12nm FinFET; engineering samples: TSMC 28nm HPC Alibaba RISC-V Turbo […]

Alibaba Unveils XuanTie 910 16-core RISC-V Processor

When Pingtou Ge (Brother Pingtou) Semiconductor Co. was founded by Alibaba in September 2018, the vision was to create groundbreaking chips for production. The company had once been Zhongtianwei, a chip company, which was acquired by Alibaba in April 2018 along with team Aha. On July 25, 2019, it was announced that Brother Pingtou had released the XuanTie 910 (Black Iron 910) 16-Core RISC-V Processor. The company has reported that the processor will be integrated into high-performance end to end 5G chips, AI, and autonomous driving applications. There are conflicting reports that the processor is also known as T-Head, although its name means Black Iron. There has been no firm release date or price as of yet. Open-source technologies are being adopted on a regular basis in China, and the XuanTie 910 is being offered to developers with encouragement to use Berkeley-based open-source ISA with very few intellectual property restrictions.
