sonic-cpp Patch Repository

Latest Updates

2026-03-30: Released patch repository version v1.0.0 based on the master branch commit 69deb02, supporting SVE2-256 optimization for the Kunpeng 950 processor.

Project Introduction

sonic-cpp is an efficient JSON library for C++ developed by ByteDance. It leverages current CPU hardware characteristics and vectorized programming to significantly enhance the performance of JSON serialization and deserialization.

This project is a patch repository contributed by Huawei Kunpeng to the sonic-cpp open-source community. It optimizes the serialization and deserialization functions in sonic-cpp using vectorized instruction sets specific to Huawei's Kunpeng processors, making it suitable for the Kunpeng 950 processor. The function interfaces remain consistent with the open-source version of sonic-cpp.
