第一台带有3D GPU的RISC-V单板计算机用“ Alibaba t-head RVB-Ice”揭示自己available for pre-order for $399以及7英寸的显示屏。该董事会基于阿里巴巴T型“ ICE”双核Xuantie C910 RISC-V处理器带有Vivante GC8000UL GPU，并宣布Android 10移植到RISC-V板上earlier this year.
Besides the dual-core RISC-V processor clocked at 1.2 GHz, the board is equipped with 4GB LPDDR4, 16GB eMMC flash, and offers Gigabit Ethernet, WiFi and Bluetooth connectivity, as well as a 48-pin GPIO header. But it lacks HDMI output, relying on an LCD interface instead, as well as full-size (Type-A) USB ports with only one micro USB 3.0 OTG port, and a USB-C port for serial console.

The board will support both Android 10 and Debian 11 with 3G GPU acceleration. The安卓10 RISC-V Github repohas not been updated for 5 months, and I can not find documentation, but there’s an email occ_thead
Last time around there was also mention of “4Kp60 HEVC/AVC/JPEG decoding ability”, but this is not listed in the specifications, and a VPU does not show up at all on the block diagram of the processor. There’s a DPU (Display Processor Unit) but that’s only for video output.
The NPU is not shown either, but锡皮德说它在场。我们也了解目前80 th单位e development kit, and shipping is expected to take place next month, and the board was announced at theCHIPS Alliance Fall Workshopyesterday:
移植Android到RISC-V - 鲁伊因陈和韩毛：Android OS在边缘和终端设备市场中有很大的份额。在过去的一年中，阿里巴巴T-Head花费了巨大的努力，将Android 10移植到RISC-V教学套装架构中。Android生态系统非常复杂。尽管我们还没有完成，但已经取得了不错的进步，尤其是在Android NDK，Bionic，Art和Chrome等一些关键方面。本届会议将分享有关如何促进RISC-V下的人的见解。目前正在Xuantie Ice Dev板上完成这项工作，该委员会的Xuantie C910 RISC-V处理器在1200MHz运行。
阿里巴巴RVB-ICE RISC-V板现在相当昂贵，因为它的制造量很低，并且软件支持可能比ARM差得多。一切都需要时间。我希望在年底或2022年初之前宣布与GPU的较低成本RISC-V董事会Beaglev星光它计划用于Q1，甚至可能使用阿里巴巴冰芯片（TBC）。
Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.
伟大的。
But at least one mini DP output might be sufficient…
尽管功能有限（软件需求写作）从年初开始很有趣。
”AMD Radeon RX 6700 XT首次在RISC-V系统上运行“
There is already an etnaviv driver in Mesa (for Vivante GPU) for years. What do you mean by software needs writing ? There are already several packages fullfilled Linux distribution for RISC-V, including Debian (so they use it here) and Ubuntu.
ARM domination means I look at a RISC-V core name and I’m not sure if it has performance like a Cortex-M, Cortex-A53, or Cortex-A72.
Lucky, if there are comparison experiences. Try to abstract from a TOPS for NPU cores what neural networks are capable of at every single SBC?
在编译具有平等配置的内核的同时，与CPU进行比较的意义是没有建立（每个人都说“是，确定，一个”）GPU（游戏，基准工具）或NPU（基准工具）核心的参考应用程序？
我认为该核心应该与Hz的A73 Hz相提并论。
是什么让你这么想的？总体上，它的时间较低，对Nezha中使用的核心进行了修订，并且该板被记忆问题所限制了，我认为它并不能阻止所有性能。除非我们在Coremarks/MHz或DMIPS/MHz中得到直接的答案，该答案可能会或可能不包括基准中的向量单元，否则我们甚至无法推测性能太多。
So, as we expected in January, it’s a patched up, production-grade Nezha. Shame it does not have Hifi4 DSP and it will take some more time before driver for this GPU gets made by Etnaviv developers, but I’ll take it over D1.
