Ingenic Semiconductor

Ingenic Semiconductor is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ingenic Semiconductor rather than just read about it. In short: 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.

Key takeaways

Ingenic Semiconductor belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ingenic Semiconductor to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ingenic Semiconductor from memory before moving on to harder problems.

Reference excerpt

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 (MXU), 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.

XBurst-based SoCs

SoCs incorporating the XBurst microarchitecture:

Adoption 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. The Jz4720 is utilized in the Copyleft Hardware project Ben NanoNote. Another popular device, the Dingoo gaming handheld, uses the JZ4732, a de facto JZ4740. Game Gadget is using the JZ4750. Velocity Micro T103 Cruz and T301 Cruz 7-Inch Android 2.0 Tablets used JZ4760. The JZ4770 SoC is used in several of the Ainol Novo 7 Android tablets and 3Q Tablet PC Qoo! IC0707A/4A40. JZ4770 SoC is also used in the dedicated handheld Neo Geo X and open source handheld GCW Zero running on OpenDingux. The JZ4780 is used in ImgTec's MIPS based single-board computer (SBC); The Creator CI20

Worked examples

Example 1 — a first encounter with Ingenic Semiconductor

Start with the simplest possible case. Write down what Ingenic Semiconductor claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ingenic Semiconductor before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ingenic Semiconductor ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ingenic Semiconductor

In research: Ingenic Semiconductor appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ingenic Semiconductor in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ingenic Semiconductor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese brands, Electronics companies established in 2005, Embedded microprocessors, so understanding it makes those chapters shorter.
In everyday life: Look for Ingenic Semiconductor outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
