Seoul, South Korea, January 12, 2022 --- OPENEDGES Technology, Inc., the world’s leading memory system and AI platform IP provider, today announced the first commercial release of mixed-precision (4-/8-bit) computation NPU IP, ENLIGHT™. ENLIGHT™, when used with other OPENEDGES’ IP solutions, provides unparalleled efficiencies in power consumption, area, and DRAM optimization.

ENLIGHT™, a high-performance neural network processor IP, features a highly optimized network model compiler that moves DRAM traffic from intermediate activation data by grouped layer partition and scheduling. In addition, it supports load balancing partition for multi-core NPU. Furthermore, ENLIGHT™'s single-core performance ranges from 0.5 ~5 TOPS at 8-bit mode and 1 ~ 16 TOPS at 4-bit mode. Since this IP core can be scaled with multi-core to reach higher performance requirements, it is highly recommended for AI inference applications.

With the industry's first adoption of 4-/8-bit mixed-quantization, customers can easily customize ENLIGHT™ at different core sizes and performance for their targeted market applications and achieve significant efficiencies in size, power, performance, and DRAM bandwidth. Based on the 4-/8-bit mixed quantization test by YOLO v3, it has been proven that 4-bit quantization can be applied to a maximum of 65% of convolution without affecting accuracy at all.

ENLIGHT™ is a production-proven IP and has been licensed in a number of verticals, including IP cameras, IoT (Internet of Things), and ADAS. Customers are licensing ENLIGHT™ along with the memory system IP, ORBIT™, as the dual solution, provides highly efficient DRAM bandwidth. OPENEDGES' memory subsystem IP, ORBIT™, consists of NoC (Network On-Chip), DDR controller, and PHY. The DDR controller (OMC™) supports DDR3/4, LPDDR3/4/4x/5/5x, and GDDR6. The DDR PHY (OPHY) supports LPDDR4/4x/5/5x along with GDDR6. As they are built to JEDEC standards, they are easily integrated with each other on an SoC (System-on-Chip).

OPENEDGES AI Computing Platform Architecture

"We are incredibly excited to release the updated NPU in the market," said Sean Lee, CEO of OPENEDGES. "The requirements for NPU rapidly change and are complicated. However, we firmly believe that our industry-leading 4-/8-bit mixed-precision scalable architecture can meet all the dynamic market requirements. ENLIGHT™ is already production-proven, and OPENEDGES has supported a complete stack of SW and SDK with memory subsystem IP, ORBIT™. Consequently, our customers’ efforts to build high-performance and highly optimized SoC exactly fit with what we provide.”
