Processor - Kneron KLM730

Kneron KL730 SoC is an ARM®-based SoC. KL730 SoC is embedded with video input controller (VIC) and video output controller (VOC) functions. To connect with LCD panels, one MIPI TX interface and one HDMI interface support video data transmission between the KL730 SoC and the LCD panel.

The NPU core is the 4th generation KDP series processor designed by Kneron® to accelerate major computing layers inside the convolutional neural network (CNN) and off-load the heavy computing from traditional CPU or GPU architecture. Its lego-like architecture services popular CNN models such as Yolo, Resnet, MobileNet, and MobileNet-SSD, and it supports a reconfigurable mechanism by using INT8 or INT16 hybrid precisions. The inference AI model can be updated over the air (by OTA).

The built-in audio codec in KL730 SoC enables playback and recording functions on most applications. There is a 3.5mm phone-jack (headphone-out and mic-in) at the edge of the board. There is also a 10/100 Ethernet transceiver (IC Plus IP101GR) to support RMII Ethernet MAC protocol. Compressed video and audio data are streamed via Ethernet.
