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.
It implements an 8-stage pipeline XBurst CPU technology consists of 2 parts: XBurst2 development was, in summer 2013, expected to be completed by the first half of 2014.
[4] However, XBurst2 was eventually introduced in 2020 in the X2000,[5] with the microarchitecture offering a dual-issue/dual-threaded CPU design based on MIPS32 Release 5.
[6] SoCs incorporating the XBurst microarchitecture:[7] XBurst1-based SoCs are commonly used in tablet computers, portable media players, digital photo frames and GPS devices: The JZ4730 CPU is used in the Skytone Alpha-400 and its variants.
