Ingenic Semiconductor

Ingenic Semiconductor is a Chinese fabless semiconductor company based in Beijing, China founded in 2005. They purchased licenses for the MIPS architecture instruction sets in 2009 and design CPU-microarchitectures based on them. They also design system on a chip products including their CPUs and licensed semiconductor intellectual property blocks from third parties, such as Vivante Corporation, commission the fabrication of integrated circuits at semiconductor fabrication plants and sell them.

XBurst microarchitecture

Early XBurst CPU microarchitectures were based upon the MIPS32 revision 1 and newer models are based on the MIPS32 revision 2 instruction set. It implements an 8-stage pipeline XBurst CPU technology consists of 2 parts:

A RISC/SIMD/DSP hybrid instruction set architecture which enables the processor to have the capability of computation, signal processing and video processing. This includes the Media Extension Unit, a 32-bit SIMD extension. All JZ47xx series CPUs with Xburst uA support MXU, except for the JZ4730.
MXU has its own register set, distinct from the general purpose MIPS registers. It consists of sixteen 32-bit data registers and a 32-bit control register. CPUs which support MXU are used in MIPS Creator single-board computers. They are also present in various tablets, handheld game devices, and embedded devices.
XBurst2 microarchitecture

XBurst2 development was, in summer 2013, expected to be completed by the first half of 2014. However, XBurst2 was eventually introduced in 2020 in the X2000, with the microarchitecture offering a dual-issue/dual-threaded CPU design based on MIPS32 Release 5.
