About BOS Semiconductors

Founded in 2022, BOS Semiconductors—short for Best of Silicon—is a global fabless semiconductor company headquartered in South Korea. Its mission is to drive mobility innovation through differentiated semiconductor technology, focusing on:

• Technology Excellence: Advanced chiplet-based SoCs for automotive and robotics.
• Distinguished Creativity: Reimagining mobility with modular, scalable architectures.
• Safety and Reliability: Meeting stringent automotive standards for functional safety and cybersecurity.

Target Markets

BOS primarily serves:

• Automotive ADAS and IVI systems – enabling real-time AI processing for safety and immersive experiences.
• Autonomous driving platforms – delivering scalable compute for Level 2+ autonomy.
• Robotics and intelligent spaces – extending AI acceleration beyond vehicles into drones and industrial automation.

Eagle-N: A Breakthrough in Automotive AI

The Eagle-N chiplet SoC, is designed to meet the growing compute demands of modern vehicles:

• Performance: Up to 250 TOPS (INT8) NPU performance, scalable to 2,000+ TOPS.
• Architecture: Chiplet-based design for modularity and cost efficiency
• Interfaces: PCIe Gen5 and UCIe for seamless integration with existing ADAS and IVI processors.
• Safety: ISO 26262 ASIL-B compliance and AEC-Q100 Grade 2 qualification.
• Security: Built-in hardware virtualization and security engine.

This architecture allows OEMs and Tier-1 suppliers to add AI acceleration without redesigning entire systems, reducing cost and time-to-market.

Why Hardware Security Matters

As vehicles become software-defined and connected, cybersecurity is no longer optional—it’s a core safety requirement. Two critical standards govern this domain:

• ISO 26262: Functional safety for electrical/electronic systems, defining Automotive Safety Integrity Levels (ASILs).
• ISO/SAE 21434: Cybersecurity engineering for road vehicles, addressing threats across the entire lifecycle.

Failure to comply can lead to catastrophic risks—from system malfunctions to remote cyberattacks that compromise steering or braking. For chipmakers, this means embedding security by design at the silicon level.

Rambus RT-640: ASIL-B Certified Security for Eagle-N

To meet these stringent requirements, BOS integrates Rambus RT-640, an automotive-grade Embedded HSM that provides:

• Root-of-Trust security: providing system wide Root-of-Trust based security functionality such as secure boot, debug and firmware update, key management and protection, attestation, SKU and feature management, cryptographic acceleration.  
• ASIL-B Certification: TÜV-SGS certified per ISO 26262, ensuring functional safety.
• Cryptographic Strength: Hardware accelerators for AES, RSA, ECC, HMAC-SHA-2, and NIST-compliant random number generation.
• Fault Protection: Detects ≥90% single-point faults and ≥60% latent faults, meeting ASIL-B metrics.
• Secure Boot & Key Management: Guarantees that only authenticated software runs on the SoC.
• Anti-Tamper Mechanisms: Protects against physical and side-channel attacks.

This integration ensures Eagle-N delivers robust AI performance with uncompromising security, enabling OEMs to comply with global safety and cybersecurity regulations.

The Strategic Impact

The BOS-Rambus collaboration sets a new benchmark for automotive silicon:

• For OEMs and Tier-1s: Accelerates deployment of advanced AI features while meeting ISO 26262 and ISO/SAE 21434 compliance.
• For Consumers: Safer, smarter, and more secure vehicles—paving the way for autonomous mobility.
• For the Industry: Demonstrates how chiplet architectures and hardware-rooted security can coexist to deliver scalable, future-ready solutions.
