Purchase a teardown report for Hesai. Maybe from Yole.
Chinese semiconductor thread II

There are some chips that it depends on the west or at least uses non-chinese chips. However, this article is written by a moron and should be regarded as such.
Please do not post random articles that are low quality.
I'm frankly really annoyed here, because I just wasted 5 minutes reading through an article full of mistakes and getting worked up.
Anything more on this topic will be deleted.
Don't know what happen to it but Huawei trademarked LinxiISA
CoreShine Intelligent launches RISC-V architecture, domestically produced self-controllable AI SSD master chip XT6160, to safeguard the security of the supply chain and industrial chain under the new situation.
In order to create a SATA enterprise-level SSD master control chip that meets the needs of domestic independent control and has excellent performance, Xinsheng Intelligence and the packaging factory fully leverage their respective technical advantages. Through a series of chip circuit design and semiconductor manufacturing process collaborative optimization efforts, they reduce leakage current and operating power consumption, improve working environment temperature and engineering application reliability, achieve substantial benefits, and achieve design goals such as high performance, high reliability, high energy efficiency and high security for enterprise and data center applications .
The XT6160 main control chip is based on the mature 28nm HKC+ process technology , which achieves an excellent balance between performance and cost. All IPs of XT6160 are domestically produced and independently controllable. Among them, the core IPs such as SATA 3.2 Controller, 4KB LDPC , NAND Flash Controller (NFC), AXI Bus, ONFI 4.2 PHY, and commercial secret algorithms SM2/SM3/SM4 are independently developed by Xinsheng Intelligent, with a self-developed proportion of more than 60%. Other IPs are from domestic IP providers , thus realizing the full process of self-development and control from IP self-development, cooperation (cooperation with domestic IP providers) to chip design, manufacturing, packaging and testing.
RISC-V architecture, independent AI core
As an important member of the China Open Instruction Ecosystem (RISC-V) Alliance, CoreShine Intelligence has gathered the power of innovation for RISC-V. XT6160 is the first SATA III (6Gb/s) controller with an independent AI core launched by CoreShine Intelligence based on the RISC-V architecture in China. It is also another masterpiece after the launch of the world's first RISC-V architecture-based, 12nm process PCIe 4.0 controller in 2022.
The XT6160's AI core monitors the working status of NAND flash blocks, predicts the optimal read voltage and flash translation layer (FTL) parameters during the life cycle of the flash block based on ML/AI algorithms, and intelligently manages, calibrates, and optimizes related parameters, thereby effectively improving SSD read and write performance, lifespan, reliability, and energy efficiency.
T Superior performance, wide temperature design
XT6160 is based on an 8-channel 32 CE flash memory interface design, supports a channel interface rate of 800MT/s, is compatible with the latest 3D TLC/QLC particles from mainstream flash memory manufacturers, and supports a single-disk capacity of up to 16TB. It uses self-developed NFC Acc and Bufman hardware acceleration functions, with 128KB sequential read/write performance of up to 565/530 MB/s, and 4KB steady-state random read/write performance of up to 98K/60K IOPS , which is better than similar products in the industry. In addition, through QoS quality control technology, the consistency of read and write performance can be maintained at more than 95%, providing users with continuous and stable performance guarantees.
Taking into account the complex environment of different application scenarios, the operating temperature design target of XT6160 is set at -40℃ to 125℃. Through the coordinated optimization of chip design and production line process, research and application of process means including adaptive voltage regulation (AVS) technology, the chip power consumption is reduced and the product life and reliability are improved in ultra-high temperature environments of 85℃, 105℃, and even 125℃.
Green and energy-saving, one core for multiple uses
XT6160 adopts low-power designs such as clock gating and multiple voltage domains. The operating power consumption does not exceed 1.5W (DRAM cache mode) or 0.8W (no DRAM cache mode).
Data security protection throughout the entire life cycle
XT6160 is designed according to the National Cryptography Administration's security chip level 2 standard specification, with active logical and physical security protection measures, effectively resisting physical dissection, probes, reverse engineering and other cracking methods, protecting the physical security of the chip itself; during the startup and operation of the chip, it loads and runs legal and trusted firmware through signature verification to prevent illegal firmware tampering and ensure the safety of chip use. The chip integrates domestic commercial cryptographic algorithms SM2/SM3/SM4 and international cryptographic algorithm AES256 hardware acceleration engine, providing full life cycle encryption and decryption security protection for user data, and has almost no impact on the performance of the SSD, effectively ensuring the storage security of data and information.
do we really need to post another low quality article from MSM with recycled talking point from think tankers?
The fact that it acknowledges Empyrean has achieved 14% domestic market share in 2023 should tell you this is not an issue. Software is not the same thing as hardware. You can just switch over much more easily.
XPEEDIC EDA is already used by Samsung and others.
Huawei Hisilicon a company with decades of experience in chip design is collaborating X-EPIC EDA. Hisilicon is one the biggest chip design houses in the world.
Primarius DTCO ecosystem already is establishing relations with Alibaba, Huawei and other big China chip companies.
DJEL OPC software is already becoming mainstream in China and already passed the verification of multiple companies.
And Semitronix Posting a healthy increase on revenue on the yield management ecosystem.
And I can go on with other companies.
Slightly tangential but Russia maintainers have been banned from contributing to the Linux kernel and have been removed from the maintainers list. There is also pressure to remove HUAWEI maintainers which would be a large blow but they’re not doing so at this time.
IMO this is a big loss for both Russia and Linux. Russian maintainers have contributed significantly to Linux. Vice versa, Russia has no realistic domestic operating systems and uses forks of Linux for anything sensitive.
Update: I’m hearing from some of my developer friends in China that this is a pretty shocking move over there. They’re worried that China itself will be banned from maintaining the Linux kernel as well.
Pretty shit move all around IMO. Gonna end up with a Euro American Linux fork and a Sino Russian one and likely shitty kernel patches back and forth to try to maintain some kind of compatibility in the long run at this rate.

These operating systems are nowhere close to as capable as Linux. Their best bet is to fork Linux but that comes with significant issues for them now as well.
