NXP Semiconductors S32V234 vision and sensor fusion processor

The S32V234 vision and sensor fusion processor is designed to support safe computation-intensive applications in vision and sensor fusion applications, including advanced driver assistance systems (ADAS), front camera systems, pedestrian and object recognition, surround view and machine learning.

The processor combines a robust, heterogeneous mix of CPU, GPU and image processors to deliver high-performance processing, vision acceleration and security features. The product integrates four Arm Cortex-A53 cores running at up to 1 GHz with a NEON coprocessor and an Arm Cortex-M4 CPU. The Cortex-M4 allows automotive operating systems to interface with external devices separate from the Cortex-A53 CPU.

The processor offers 4 MB of on-chip system RAM and two 32-bit DRAM controllers with support for LPDDR2/DDR3/DDR3L, all with ECC memory. For image processing and vision capabilities, the device includes dual APEX-2 vision accelerators, a GC3000 3D GPU with surround-view support, MIPI CSI2 and parallel image sensor interfaces, and an embedded image signal processor. It also offers an array of connectivity features, including Gigabit Ethernet, Zipwire serial interface, dual CAN-FD interfaces, dual-channel FlexRay communication and a PCI Express (PCIe) lane.

Security capabilities include an on-the-fly AES decryption engine (OTFAD) and a Cryptographic Service Engine (CSE) that meets Secure Hardware Extension (SHE) protocol specifications. The device also features automotive safety compliance capabilities developed through NXP’s SafeAssure program, which helps manufacturers achieve system compliance with ISO 26262 and IEC 61508 functional safety standards.

The processor is supported by the SBC-S32V234 Vision Prototype Kit, which offers options for Linux (Yocto) and AutoSAR operating systems. The kit is supported by a complete series of enablement tools and the S32 Design Studio integrated development environment (IDE).
