CEO Sean Lee gives the lowdown in interview

The CEO of AI chip platform startup Openedges Technology expects the company to experience double to triple growth per year going forward from high demand for its IP solutions.

The company launched its mixed-precision (4/8bit) computation neural network processing unit (NPU) IP dubbed Enlight last month.

Previous NPU IP for edge networks mostly used 8bit as lowering the bit could reduce power consumption and increase surface area efficiency could also lower accuracy, Openedges CEO Sean Lee explained.

Enlight, by processing as much computation in 4bit as possible while using 8bit for tasks requiring high-precision, can reduce power consumption while retaining the benefits of an 8bit NPU IP, Lee said.

Enlight has been verified in uses such as security cameras and advanced driver assistance systems, the CEO said.

The NPU IP can be used together with Openedges' memory system IPs such as those for memory interconnector, DDR controller and DDR PHY, Lee said.

For NPUs to perform optimally, they must be paired with a memory system that can save and provide high-density data, the CEO said.
