Image Signal Processing for Automotive and Industrial Applications

Mali-C71AE is Arm’s highest performance image signal processor (ISP) developed for the emerging smart automotive systems and industrial markets. Delivering key visual information to both computer vision (CV) systems and human display for clear and convenient viewing, Mali-C71AE is the first product in the Mali Camera series of ISPs with built-in features for functional safety applications.
 

• Multi-Camera Support
  • Mali-C71AE supports up to 4 real-time camera inputs or 16 camera streams from memory. Supporting simultaneous inputs from a mix of sensor and CFA types operating in a variety of modes allows the system developer to select from a wide range of sensors from various suppliers.
• Advanced Noise Reduction
  • Mali-C71AE contains advanced spatial (2D) noise reduction ("sinter®"), per-exposure noise profiling and chromatic aberration correction, providing optimized image data for computer vision applications and the best-quality image to the vision system for display to the human operator.
• Every Pixel Reliable
  • Mail-C71AE provides real-time safety features for advanced driver assistance systems (ADAS) and human-machine interface (HMI) applications, enabling system-level functional safety compliance. With over 400 dedicated fault-detection circuits, built-in self-test (BIST), and CRC on critical data paths, every pixel is tagged for reliability.
• Robust Safety Capabilities
  • The safety features in Mali-C71AE allow it to meet ASIL B/SIL 2 diagnostic requirements and ASIL D/SIL 3 for the avoidance of systematic failure. This can enable safe vision use cases, such as ADAS or industrial mobile robotics.
• Dynamic Range Management
  • Capable of processing 24 bits of dynamic range to capture every detail, from bright sunlight to deep shadows, Mali-C71AE features independent dynamic range management for optimum human vision (display) and for CV applications.
• Special Datapath Considerations
  • Mali-C71AE provides reversible transforms where not required for human viewability, possible “suspect” pixels tagged by location, region-of-interest crops, and planar histograms for further CV system analysis. Ideal for advanced CV use cases, including ADAS and industrial mobile robotics.
