High-performance 32-bit Superscalar Processor

C810 utilizes a 10-stage superscalar pipeline, with a standard memory management unit, and can run Linux and other operating systems. C810 utilizes a 2-issue and 5-execution out-of-order execution architecture with a single/double-precision floating point engine. It can be further equipped with other functions such as a high-performance vector calculation engine and secure execution technology. It is suitable for application fields requiring high processor performance such as secure monitoring and artificial intelligence.
