Black Sesame Intelligence launches the first chip in the Wudang series using a 7nm process, enabling a single SoC to "make big use of small materials"

About 3-4 years ago, Black Sesame Intelligence re-examined its strategic direction and launched the research and development of a new series of products 2 years ago. Now, this product has finally been released, which is the first chip product of the Wudang series - the C1200 smart car cross-domain computing chip platform. From this product, it is not difficult to see that Black Sesame Intelligence’s prediction that year was that intelligent driving would become standard equipment, the electronic and electrical architecture would evolve towards a centralized system, and the demand for cost-effectiveness would become increasingly stringent.

At a press conference on April 7, Shan Jizhang, the founder and CEO of Black Sesame Intelligence, announced that the release of C1200 marked the company’s strategic positioning. Convert from autonomous driving computing chips to smart car computing chips. In an unprecedentedly fierce price war, Black Sesame Intelligence wants to use its cross-domain computing chip platform to demonstrate its ability to "save" and even "open up" the cost of smart cars.

What needs to be rewritten is: "Three-step" strategy

Continuous expansion of product lines

"Unprecedented In the fierce competition, we welcome all business partners to compete and cooperate openly. Only in this way can China's intelligent driving industry develop healthily," Shan Jizhang said, in order to build full-stack technical capabilities and create a better environment. Ecologically, Black Sesame Intelligence has formulated a "three-step" strategic plan while adhering to its Tier2 role:

• The first step is to focus on autonomous driving computing chips and solutions to realize product The commercialization of the vehicle has been implemented to form a complete technology closed loop;

• According to the development trend of automotive electronic and electrical architecture, the second step is to expand the product line to cover more computing nodes in the car, forming Combination of multiple product lines

• The third step is to continuously expand the product line to cover the needs of more cars and provide customers with a variety of automotive software and hardware solutions and services based on our chips.

Black Sesame Intelligence’s product line currently covers two important areas: autonomous driving and cross-domain computing. The first is the Huashan series of products for autonomous driving scenarios. The A1000 chip can support the latest BEV algorithm and meet the needs of L3 and below autonomous driving scenarios. The second is the Wudang series of products for cross-domain computing scenarios, which can meet the needs of different domains such as smart car cockpits and smart driving, and have the ability to integrate multiple domains

The "cost reduction capability" has become the two major products The competitive advantage of line-focused products. Shan Jizhang said that the price competition in the new energy vehicle industry this year is fierce, and cost pressure is transmitted to the entire supply chain. Reasonable computing power and high cost performance have become the mainstream of the autonomous driving market.

Currently, Black Sesame Intelligence has completed a number of technological innovations focusing on cost reduction and efficiency improvement, including car-grade neural network technology that achieves twice the cost performance of similar products in the industry, which can improve chip yield while reducing Low-cost packaging technology, new automotive-grade computing chip architecture systems that can maximize chip performance, etc.

Black Sesame Intelligence released a parking and parking integrated smart driving domain control solution at last week’s Electric Vehicle 100-person Conference, which supports 10V (camera) NOA function, and the cost is controlled within 3,000 yuan, and it also supports physical computing power of more than 1,000TOPS

Cross-domain computing platform "Wudang"

Four major " "Moves" Inventory

"Judging from the computing requirements of a smart car, its computing power types are divided into seven categories: general CPU, AI neural network processing, image rendering, dedicated CV calculation, audio Sound effect processing and efficient and secure real-time computing power."

Ding Ding, Vice President of Black Sesame Intelligent Products, said that the extremely fast data exchange infrastructure (ESDE) independently developed by Black Sesame Intelligent can support seven different computing capabilities. , and can manage the corresponding data efficiently and flexibly, thereby providing a computing platform with better performance, higher cost performance, and higher integration for the new generation of electronic and electrical architecture

Specifically, first, the ESDE architecture can safely isolate computing power combinations required by different functional safety levels. Secondly, it can process and transmit large traffic data with low latency to make full use of computing power, making the computing power specifications more than just decorations. The Wudang series product line launched by Black Sesame Intelligence this time is based on Created by ESDE, "new, accurate, strong and high" are its four highlight "moves".

• First of all, the Wudang series adopts an innovative fusion architecture, using heterogeneous isolation technology to match and combine different computing power according to different scenarios, specifications and security requirements to support the flexible development of automotive electronic and electrical architecture

• Secondly, this product line targets the L2-level intelligent driving and converged computing application market. Only one SoC can provide human-computer interaction, driving and parking integration, and data exchange. Capability

• The third is the powerful family design, which is based on advanced technology to ensure that the product can respond to different computing needs, meet the needs of various scenarios through a set of SDKs, and at the same time make the development tools into a family

• Black Sesame Intelligence’s third-generation automotive-grade SoC provides effective protection in terms of security, and has been successfully tape-outed in one go. It is understood that the Wudang series platform has greatly optimized the previous generation design, which not only significantly improves performance, but also has ASIL-D Safety capabilities and Security capabilities for regional markets around the world

Single chip supports multiple scenarios

"It's not about throttling, but about open source"

The C1200 based on the 7nm process is the first in the Wudang series. A chip that uses the automotive-grade high-performance CPU core A78AE (performance up to 150KDMIPS) that supports lockstep and the automotive-grade high-performance GPU core G78AE to provide powerful general-purpose computing and general-purpose rendering computing power.

Moreover, the chip has built-in mature and high-performance Audio DSP module and a new generation of self-developed NeuralIQ ISP module that can process 1.5G pixels online per second, providing the industry's highest MCU of 32KDIPMS. Computing power, it can process the input of more than 12 high-definition cameras at the same time, and supports high-speed MIPI.
