AIROHA hugs RISC-V for building the first “golden triangle” architecture for 10G-PON

With its deep expertise in fixed network, Airoha Technology designed the multiple-function NPU based on open standards delivering highest flexibility. Over the past decades, many industries have gained success and benefits in transiting from a proprietary architecture to open standards. The RISC-V instruction set architecture (ISA), based on open collaboration and shared technical investment, is now the 3rd largest ISA in the market, and is becoming one of the new mainstreams in processors. The fixed line broadband industry now is facing the need for wider bandwidth to bring more innovative applications and the need to migrate from traditional infrastructure to fiber-optical architecture. Accordingly, it is also imperative and inevitable now for the broadband operators to adopt an open technical framework to lay the foundation for their long-term competitiveness.

The whole new AN7581 series SoC is designed to deliver both flexibility and performance. In addition to a 4-core CPU based on ARM architecture, an 8-core multi-function NPU based on RISC-V open platform is tactically employed to reduce CPU load and achieve unparalleled performance and flexibility in computing and data transmission.
