ZC.MuNiu lightweight basic software product provides an effective solution for resource-constrained automotive electronic controllers. This product complies with international standards such as AUTOSAR and features an upper-level configuration tool based on the AUTOSAR ARTOP architecture. It supports communication, diagnostic, and network management specifications for vehicle manufacturers including SAIC, FAW, Geely, GAC, Changan, GreatWall, and BAIC. The platform primarily includes: communication protocol stacks (CAN), diagnostic protocol stacks (UDS), network management (AUTOSAR), calibration protocol stacks (XCP/CCP), storage protocol stacks, and complex driver modules. It is complemented by ZC Bootloader update program and upper-level tools, enabling customization and further development according to specific customer project requirements. In addition to providing basic software products, ZC Technology also offers development services for the implementation of controller basic software functions.

ZC.MuNiu lightweight AUTOSAR CP product is primarily designed for controllers such as fuel pumps and water pumps that demand high levels of integration, reliability, power efficiency, and cost-effectiveness. These controllers typically utilize small, highly integrated, automotive-grade chips, which are part of a low-memory chip platform, with Flash resources typically less than 512KB and RAM resources less than 32KB. Therefore, the lightweight basic software product ensures strict compliance with OEM specifications while eliminating a large number of redundant components from the traditional AUTOSAR architecture (see Figure 1), retaining only the necessary modules for the core functions of AUTOSAR (see Figure 2), thereby effectively reducing system complexity and resource consumption. Leveraging the powerful configuration capabilities of the ZC.MuNiu configuration tool, rapid configuration and adjustment of functional parameters for each module are achieved, significantly enhancing development efficiency and system operational flexibility on resource-constrained platforms.

Resource-constrained SoCs are being used in automotive electronics, industrial control and other fields. Taking the MOTIX TLE988x and TLE989x series launched by Infineon as an example, this series of chips have outstanding performance among similar products due to the significant advantages of higher performance and integration of more resources in a smaller area. However, the traditional AUTOSAR architecture contains a large number of modules and redundant features that make it difficult to adapt to such resource-constrained hardware platforms. In order to fully utilize the performance of these small chips while maintaining the integrity of AUTOSAR's basic functionality, ZC has launched the lightweight AUTOSAR CP base software product. Based on the in-depth trimming of the original full-volume AUTOSAR CP and the convenience of the ZC.MuNiu configuration tool, the product has successfully created a lightweight solution for the TLE989x series (e.g., TLE9891). At present, the solution has achieved mass production, providing the industry with a mature and reliable option to meet the demand for miniaturization.

In AUTOSAR architecture engineering, the COM (Communication) module is not only the core carrier for implementing automotive electronic communication functions, but also a key module in the entire CP product architecture. Below, we will focus on the COM module and briefly introduce its lightweight implementation approach in the entire product development process, from functional design to code trimming.

Ø  Design lightweight feature list of COM module

In the AUTOSAR architecture, the COM (Communication) module is the core component of the communication protocol stack, and its core functions can be summarized in the following four points:

1. Signal routing and mapping: signal-level routing and gateway functions.

2、Communication protocol processing: PDU grouping/unpacking and management of communication attributes.

3、Communication scheduling and control: event or cycle triggered signaling.

4、Communication service support: providing standard interfaces for upper layer RTE, diagnostic communication, error handling, etc.

 We have retained the basic functionality of the COM module, including maintaining signal sending and receiving, data interaction and CAN communication support. Non-essential redundant features such as complex gateway routing, support for dynamic signals, invalid signals, RC signals, and other minor scenarios are stripped out. For project OEM specifications, customised features are extended on top of the basic functionality, both with minimal code overhead (~1KB ROM) to achieve complete coverage of communication requirements.

Ø  Tailor strategy for COM module

Traditional COM modules are designed with over 40 functional functions to accommodate diverse and complex scenarios, including operations such as protocol data unit (PDU) grouping, signal management, and dynamic signal handling. However, many of these features are tailored for less common scenarios, offering limited value in engineering applications while consuming excessive resources. This contradicts the core principles of lightweight AUTOSAR, which aims for streamlined and universally applicable high-frequency functionality. Therefore, through feature screening and interface integration, we retained over 10 key interfaces, covering core processes such as signal unpacking and repackaging, as well as the transmission and reception of protocol data units. This ensures the basic requirements for CAN communication and UDS diagnostics across the entire project.
