Feature: Industrial applications


certifi able hardware and soſt ware solutions. To simplify their development, manufacturers like NXP and MicroSys Electronics provide specifi c platforms and tools. Future-ready hardware components such as system-on-modules (SoMs), operating systems and frameworks for real-time control ease the task. Developers are also provided with pre-validated hardware, extensive security features and optional middleware, to signifi cantly reduce their development eff ort and risk. Pre-confi gured SoMs reduce design


complexity by providing key components in an application-ready module. One such module, well suited to building AGVs and AMRs, is the miriac MPX-S32G399A from MicroSys Electronics (Figure 1). It is built around the S32G399A processor from NXP, and features other eight 1.3GHz Arm Cortex-A53 cores and four Arm Cortex-M7 cores – for added functionality, including a safety package for safety-critical systems. T e NXP S32G399A is a vehicle


network processor, which combines ASIL-D safety with high-performance application processing, along with extensive network acceleration. T e device belongs to the broader family of processors from NXP, the S32G3, aimed at modern vehicle architectures, including service-type gateways, vehicle computers, domain controllers, zonal processors, safety functions, and more. NXP supports its processor family with a broad range of soſt ware and the S32 Design Studio IDE. T e S32G399A NXP CPU comes with 4GB LPDDR4 32-bit memory, 64MB QSPI Flash memory, and 32GB eMMC storage. T e integrated Hardware Security Engine (HSE) provides secure boot functionality, and the Low Latency Communication Engine (LLCE) accelerates CAN, LIN and FlexRay message processing. AI accelerators such as the Hailo-8


can be integrated via the onboard M.2 connector, enabling faster data processing and comprehensive sensor fusion.


Additional capabilites The miriac MPX-S32G399A SoM can be combined with the miriac MPX- S32Z2 SoM built around another NXP

CPU, the S32Z2, for controlling external peripherals like image sensors, LiDAR or radar in real time, and to process and analyse the recorded data. To further reduce design complexity,


developers can use the single-board computer (SBC) from MicroSys Electronics, called the miriac SBC- S32G399A; see Figure 3. It includes pre- integrated software and operating systems such as Linux, VXWorks (on request), as well as other functionalites. The SBC provides advanced CPU


interfaces for easy connectivity, but it also integrates automotive buses like FlexRay, LIN, or CAN, making it highly suitable for innovative automotive and sensor fusion applications for industrial setups. To meet the AGV and AMR

communication requirements, the SBC offers a wide range of Ethernet interfaces, some with Time-Sensitive Networking (TSN) support, including a 1GbE, 1000BASE-T1 and 6x 100BASE-T1. In addition, there are also interfaces such as USB 2.0, 18x CAN-FD, 8x LIN, 2x FlexRay, GPIOs, and JTAG. To ease the challenge of building


mobile robots for developers, MicroSys also provides an application-ready Linux operating system on its platform. This allows developers to fully concentrate on their application.

SMARC or proprietary? Compared to an open computer-on- module standard like SMARC, MicroSys can fully leverage the performance of the NXP CPU with its proprietary standard. Not all CPU interfaces can be made externally available via SMARC, as the standard only supports certain pinouts. In contrast, the MicroSys SoM


exposes all critical interfaces – such as all Ethernet and CAN ports – enabling a scaleable number of interfaces and maximum CPU performance. It also offers optional CPU monitoring via a supervisor. The MicroSys SoM’s modularity


shortens development time and costs. Integrated security features allow compliance with industry-specific safety and regulatory standards.
