− | '''Godson 2''' ('''龍芯2''') is a family of {{arch|64}} [[MIPS]] | + | '''Godson 2''' ('''龍芯2''') is a family of {{arch|64}} [[MIPS]] performance desktop processors developed by the [[Institute of Computing Technology of the Chinese Academy of Sciences]] (ICT) in 2003. The Godson 2 processors are now developed by [[Loongson Technology]] (which was co-founded by ICT) and sold as low-power embedded and desktop processors. The Godson 2 is famous for being the first [[Chinese]] developed {{arch|64}} microprocessors. |

− | The Godson 2 | + | The Godson 2 microprocessors are designed as a general purpose {{arch|64}} that implements a [[MIPS64]]-like instruction set (Note that at the time ICT was not a MIPS licensee). Many improvements were done in Godson over {{\\|Godson 1|its predecessor}} such as a wider pipeline capable of [[instruction fetch|fetching]] and [[instruction decoding|decoding]] four times as many instructions per cycle. |
− | + | Initial Godson 2 models were fabricated on a 6-metal [[0.18 µm process]] [[CMOS]] technology using automatic placing and routing. Later models enjoyed a series of [[process shrinks]]. The Godson 2 has integrated additional features over the years from just a CPU to an entire SoC incorporating a [[PCI]]/[[PCIX]] controller, [[memory controller]], [[SPI]]/[[UART]]. Those processors utilized the a [[HyperTransport]] bus for the [[southbridge]]. Most recent models integrated much of the southbridge on-die as well including [[PCIe]], [[SATA]], and a [[USB]] controller as well as multimedia support (GPU, dual display, audio, and media decoders). | |
