D1

Allwinner D1 (sun20iw1p1, also know as D1-H) is the first SoC of Allwinner which is based on a RISC-V core. D1 features single RV64GCV core XuanTie C906 from T-Head Semiconductor (subsidiary of Alibaba) and an additional 600 MHz Tensilica HiFi4 DSP.

On August 2020, Allwinner announced a cooperation with T-Head (PingTou) to jointly produce a RISC-V SoC then CNX Software told about an upcoming RISC-V SoC and a SBC from Allwinner on November 2020.
