The Tianqiao-90 is a high-performance commercial-grade RISC-V CPU core. It is engineered for applications demanding robust computing power such as data centers, PCs, mobile devices, and high-performance networking communications. Employing an 11+ stage pipeline, five dispatch mechanisms, and deep out of order execution, the CPU core supports the RISC-V RV64GCBH extensions. It has undergone extensive pre-integration and verification, simplifying SoC development with its support for single-core, dual-core, and quad-core configurations. The SPECint2006 can reach 9.4/GHz, making it a potent choice for advanced computations in a wide array of technological environments.
