In all mobile terminal products, whether it is Apple, Samsung, Qualcomm, Mediatek, or Huawei Kirin chip, must be authorized by ARM company, because all mobile phone chips must use ARM chip architecture, ARM company provides CPU, GPU and other chip architecture, Xiaomi's surging chip is no exception.
Of course, there are also chip manufacturers such as Apple and Qualcomm, which do not directly use the GPU chip architecture provided by ARM, but use their own self-developed GPU chip architecture.
Surging chip is exactly an SoC, then what is SoC? SoC is short for System on Chip, also known as system-on-chip, is a micro-miniature system, because of the basic attributes of mobile phone communication, SoC is generally divided into two parts, BP(Baseband Processor) and AP(Application Processor). BP is what we often call a baseband chip, specifically taking Xiaomi's surging S1 as an example
The paper S1 This SoC includes the central processor is what we usually call the CPU, which is composed of four 2.2GHz Cortex-A53 large core and four 1.4GHz Cortex-A53 small core. In addition, there are common GPU(graphics processor)MaliT860, DSP (digital signal processor), ISP (image signal processor), Modem communication module and so on. These modules manage, organize, coordinate, and distribute the tasks of each module through a complex heterogeneous computing system to solve problems quickly and efficiently and make performance and power consumption more balanced.
As far as the CPU part is concerned, the 8-core big.LITTLE structure is more common in mobile chips, and the power consumption is balanced according to the scheduling of the load. Cortex-A53 is a microarchitecture launched by ARM, which is more common, 8-core Cortex-A53 is generally used as a low-end processor, and the current mid-end processor Snapdragon 625 and Kirin 655 are such architectures. Therefore, the surging S1 can be regarded as a mid-end chip, but the process used is not the same as that of Snapdragon 625 and Kirin 655, and the 28nm process is two generations behind, so the power consumption will be worse. The GPU part 4-core Mali-T860 also belongs to the mid-range positioning. We can see that the storage interface is EMMC5.0 and LPDDR4, which is also the mid-end interface, high-end chips generally support UFS2.1 and LPDDR4.
In the baseband part, Lei Jun said that the baseband can be upgraded OTA, what is this? This is a Software DSP solution, derived from the SDR technology of Lianxin. In November 2014, Datang Telecom issued an announcement that the company's wholly-owned subsidiary Lianchin Technology Co., Ltd. signed the \"SDR1860 platform technology transfer Contract\" with Beijing Songguo Electronics Co., LTD., and licensed the SDR1860 platform technology developed and owned by Lianchin Technology to Beijing Songguo Electronics Co., Ltd. at a price of 103 million yuan.
From Xiaomi's official introduction to the 5C, we can see that this chip does not support Unicom and Telecom 3G, as well as FDD-LTE, which is a bit behind.
On the whole, the surging S1 is a mid-end chip, but it lags behind and friends in terms of process, power consumption may be slightly larger, and there is more to go in baseband.
It is said that the next generation of Xiaomi Surging chip S4, using TSMC 7nm process, independently developed mi200 cpu core architecture, while the GPU uses the latest domestic Imagination based on Furian architecture developed Series 8XT. This is originally intended to be used as a powerful GPU Apple A11 processor, but because Apple A11 used its own research and development GPU caused the GPU to lose most of the order, millet may be cheap to pick up the cheap. The overall performance of the surging S4 can touch the Kirin 980 tail and easily hit the Snapdragon 845
