SWIFT DDS Product Architecture

Green Engine SDK

Further simplify the upper-level applications development. Developers only need to focus on the intelligent driving logic and algorithms. Automatically parse interactions among the upper-level applications, generate middleware glue codes and complete system integration, greatly improving the development efficiency. Compatible with common intelligent driving chips, help fast integration and verification of intelligent driving products, enable OEMs quickly build reliable software platforms for volume production.

Key Advantages

All middlewares used in automatic system integration are from Greenstone, which fundamentally guarantees the compatibility between middleware modules and ensures the high stability and reliability of the system.

Provide all key services for upper-level applications, can avoid additional adapting costs in the process of integrating middleware modules from different suppliers, and can significantly shorten the integration time.

Toolchains

Core tools: DDS configuration, DDS monitoring, DDS recording/replaying, scheduling configuration, scheduling orchestration, scheduling profiling, EM container utility, EM monitoring, etc. Cover every aspects of the V-model of software engineering, helping OEMs accelerate the building of intelligent driving software platforms and the debugging/integrating of applications.

Key Components

User-friendly GUIs

Case 1 - Deployment in all domains by a Traditional OEM

SWIFT DDS enables seamless communication across the domain of intelligent driving, cockpit, and body chassis.

Enables interconnectivity between multiple chips and multiple operating systems in the complex communication scenarios of the SoC/MCU hybrid architecture.

The highly efficient toolchain helps customers simplify system integration and version iteration management.

Application Cases

Case 2 - L2+ ADAS Domain Controller of Continental AG

SWIFT DDS supports distributed communication in various modes between multiple nodes, including J5, TDA4 Main-A, Main-R, and MCU-R.

The scenarios are complex, including over 20 processes and over 200 topics. Each process has more than 20 DataWriters and DataReaders on average.

Using the Green Engine to achieve flexible configurations for communication, scheduling and execution management, enabling customers to quickly integrate, deploy, and validate their algorithms.

Established in 2020 by a group of experienced professionals graduated from Tsinghua University in the fields of digital communication, computer chips, operating system, middleware, smart driving and AI, Greenstone is dedicated to building a highly reliable and secure software infrastructure that can support real-time data communication and deterministic program execution for complex systems, which consist of multiple data sources, heterogeneous computing chips and various upper-level applications. Based on a solid foundation of IPRs, we contribute to smart vehicles with key proprietary middleware products and a highly scalable middleware platform, helping customers construct low-cost high-reliable autonomous driving software platform in a much shorter period of time. Our objective is to provide an industrial leading software foundation for "Software-Defined Vehicles“.
