Unisoc, formerly known as Spreadtrum, has unveiled the world’s first security chip based on the RISC-V open instruction set architecture. This chip named the E450R is designed to enhance performance in security algorithms.
The E450R consists of the following features:
- Asymmetric Cryptographic PKE Algorithm Engine: The E450R works 50% faster than its predecessor in asymmetric cryptographic operations. Even with increased key lengths, it maintains robust security without sacrificing speed.
- Transaction-Based Applications: The chip offers a 50% improvement in typical transaction-based applications, making it suitable for high-demand environments where quick processing is crucial.
- Non-Volatile Memory (NVM) Speed: The E450R boasts a 15% boost in erase/write speed for its NVM. This efficiency is beneficial for applications requiring frequent memory operations.
- Tailored Microarchitecture: Unisoc’s use of the open-source RISC-V ISA allows them to tailor processing cores for specific workloads, offering better performance at lower power compared to traditional approaches.
- Software Optimization: The chip’s tailor-made microarchitecture reduces application code size by 30% and speeds up application load time by 120%, crucial for real-time applications.
- Certifications: The E450R has achieved several certifications, including National Cryptography Level 2, UnionPay chip and embedded software security certifications, and CCRC IT EAL4+ certification.
