Loongson tears up MIPS: new CPU uses old code

Although Godson claims its The latest 3A5000 and 3C5000 processors Is based on its Proprietary architecture developed in-house And no longer relying on the MIPS architecture, the code the company uses to enable the new CPU in Linux is actually the same as the code it uses for MIPS-based chips. In addition, even on paper, CPU developers cannot show software developers the advantages of their architecture.

Historically, Loongson’s CPU relied on the company’s various types of LoongISA architecture, which is a custom subset of the MIPS64 architecture. This strategy allows the company to maintain compatibility with programs designed for MIPS64, including software for high-performance computing applications, while introducing its own extensions to improve the performance of contemporary applications.
