This talk will give first a brief introduction to Loongson Processors.
The Loongson project is the first attempt to design high performance general-purpose microprocessors in China. The latest Loongson-2F is a 1GHz, 64-bit four-issue, out-of-order execution RISC processor that implements MIPS64 instruction set. Loongson-2F has been volume produced and used in many areas such as low-cost PC and embedded applications.
After an analyzing of technical and industrial trends of CPU, this talk will also introduces the Loongson-3 which is a multi-core processor based on the 64-bit superscalar Godson-2 CPU core. It takes a scalable CMP architecture in which processors and global addressed L2 cache modules are connected in a distributed way and coherence of multiple L1 copies of the same L2 block is maintained with a directory-based cache coherence protocol. The CPU core of Loongson-3 is enhanced to support efficient X86 to MIPS binary translation, and to optimize performance, power consumption, reliability and debug methods. |
