The editor will share with you what structure Godson refers to. I hope you will gain something after reading this article. Let's discuss it together.

Godson is the MIPS architecture. On the basis of more than 500 instructions in MIPS64 architecture, Godson instruction system LoongISA has added nearly 1400 new instructions in four aspects: basic instructions, virtual machine instructions, binary translation instructions for X86 and ARM, and vector instructions.

Godson is the MIPS architecture.

Godson is a general CPU independently developed by the Institute of Computing, Chinese Academy of Sciences. it uses an independent LoongISA instruction system and is compatible with MIPS instructions. Longxin No. 1, which was born on August 10, 2002, is the first general-purpose high-performance microprocessor chip with independent intellectual property rights in China. From 2001 to now, Godson has developed three series of processors and bridge series of Godson, which have been widely used in government and enterprise, security, finance, energy and other application scenarios. Godson 1 series is a 32-bit low-power, low-cost processor, mainly for low-end embedded and dedicated applications; Godson 2 series is 64-bit low-power single-core or dual-core [5] series processors, mainly for industrial control and terminals; Godson 3 series is a 64-bit multi-core series processor, mainly for desktops and servers.

Godson architecture:

On the basis of more than 500 instructions in MIPS64 architecture, Godson instruction system LoongISA has added nearly 1400 new instructions in four aspects: basic instructions, virtual machine instructions, binary translation instructions for X86 and ARM, and vector instructions.

While obtaining the permanent license of MIPS, Godson has expanded itself:

148LoongEXT instructions

5 LoongVM instructions

213 LoongBT instructions

1014 LoongSIMD instructions

Expand the original 527 instructions of MIPS to 1907, and develop into Godson's own LoongISA, which can expand the instruction set independently and choose the development direction independently. Godson insists on writing its own source code and designing its own processor core. The advantage is that it has the right to independent development, but the technical threshold is also the highest, so it is Hard (difficult) mode.
