HiSilicon Hi3731V110 32-bit RISC-V processor is made for Full HD televisions

We’ve previously covered Hisilicon Hi3861V100 32-bit RISC-V microcontroller, but HiSilicon Hi3731V110 32-bit RISC-V processor designed for Full HD televisions, the company has gone up the scale with its RISC-V offerings.

The processor is equipped with an M-LVDS interface for TCON panels, CVBS output, YPbPr, VGA, and multiple HDMI 1.4 video inputs. The processor also comes with a 1080p30 VPU supporting H.265, H.264, MPEG4, MPEG2, and other codecs.

The company further explains the processor is suitable for 2-layer PCB designs, supports various low power modes, as well as wakeup by HDMI or VGA. HiSilicon provides Huawei LiteOS real-time operating system for the processor, and we should not expect fancy user interfaces since there’s no 3D GPU, only a 2D GPU.

HiSilicon Hi3731V110 RISC-V processor will probably be reserved for entry-level televisions for mainland China and emerging markets. A few more details may be found on the product page.
