RISC-V based Allwinner chip to debut on $13 Linux hacker boardAlibaba’s T-head subsidiary amd Allwinner have produced a single-core, RISC-V-based XuanTie C906 processor with MMU that can seem on a sandwich-style, Linux-driven, $12.50 Sipeed SBC due in two months.

In July, 2019, Chinese language tech big Alibaba Group stunned the business with essentially the most highly effective RISC-V structure SoC design thus far: a 16-core, 2.5GHz XuanTie 910 (XT 910). Now Alibaba’s RISC-V-focused T-Head subsidiary is collaborating with Allwinner to introduce a single-core, 1GHz XuanTie C906 (RV64GCV) RISC-V processor designed to run Debian Linux. A Sipeed dev package will arrive within the coming months for $12.50 that comes with an Allwinner compute module constructed across the XuanTie C906.

The information got here in a tweet from Sipeed, which earlier this yr launched a $24.90 Sipeed MaixCube dev package that includes a Kendryte Okay210 RISC-V with 1TOPS NPU. Though the Kendryte Okay210 nominally helps Linux, it lacks a Reminiscence Administration Unit (Unit), making it a significantly better match for FreeRTOS. The XuanTie C906 does embody an MMU, nevertheless, and is designed to run Linux. Like different RISC-V processors thus far, it lacks a 3D GPU.

As famous by the CNXSoft publish that alerted us to the XuanTie C906 and new Sipeed SBC, Alibaba’s T-Head and China-based Arm chipmaker Allwinner introduced a collaboration wherein Allwinner will manufacture chips primarily based on the royalty-free, open-spec RISC-V XuanTie IP. The companions projected 50 million items would ship within the subsequent three years, concentrating on industrial management, sensible dwelling, and shopper electronics.

T-Head has posted a product web page and simplified block diagram for the 22nm fabricated XuanTie C906, a 5-stage, in-order pipeline chip with as much as 64KB instruction and information cache, interrupt controllers, and a 128-bit AXI 4.zero bus. The as much as 1GHz, single-core processor offers 2.Four DMIPS/MHz(O2) and three.eight CoreMark/MHz(O3) efficiency. This compares to 7.1/MHz CoreMark for the XuanTie 910 and 5.1/MHz CoreMark for the SiFive U74 IP discovered on its FU740 SoC and new HiFive Unmatched Linux dev board.

The specs for the unnamed Allwinner module and Sipeed SBC are nonetheless incomplete. In accordance with Sipeed responses to questions on Twitter, the board will provide not less than 256MB however lower than 1GB DDR3 RAM through a single slot with “each 16/32-bit doable, depends upon value.” CNXSoft, which additionally posted a render of the Allwinner compute module (see above), lists 64MB to 256MB DDR3 through a PoP module.

The Sipeed board primarily based on the XuanTie C906 will provide H264/H.265 video encoding and media I/O together with HDMI, RGB, DVP, and MIPI. The board will present a microSD slot, USB host and OTG ports, and a GMAC (Gigabit Media Entry Controller) to allow a GbE port. CNXSoft says there can be elective WiFi/ BT and a Debian-based distribution referred to as Tina OS.

Allwinner has lengthy been a frontrunner in Arm SoCs used on Android media gamers and set-tops, in addition to Linux/Android powered hacker boards. Though Rockchip, Amlogic, and others have made inroads on the excessive finish, Allwinner remains to be essentially the most broadly used processor vendor among the many 136 open-spec boards present in our Jan. 2020 Catalog of Linux hacker boards.

T-Head, which can also be referred to as Pingtouge, was shaped from a number of smaller processor design corporations, together with C-Sky Microsystems. C-Sky was recognized for its early, $6 C-SKY Linux Growth Board primarily based on a 574MHz, RISC-V structure GX6605S CK610M SoC.

Additional info

The unnamed Sipeed SBC utilizing the upcoming Allwinner module primarily based on an Allwinner/T-Head XuanTie C906 (RV64GCV) ought to change into out there in 1-2 months for $12.50, in accordance with this Sipeed tweet and responses. Extra info could finally seem on the Sipeed web site and/or Allwinner web site. Extra on the XuanTie C906 could also be discovered on this T-Head product web page.
