Sierraware Announces the Availability of SierraVisor and SierraTEE for 64-bit ARM Architectures

Hypervisor and Trusted Execution Environment (TEE) for big.LITTLE, Cortex-A53, and Cortex-A57

Sunnyvale, CA, February 4, 2014 - Sierraware, the embedded virtualization company, today announced the release of SierraVisor and SierraTEE for 64-bit ARM silicon. The SierraVisor Hypervisor for 64-bit ARM architectures allows multiple operating systems, such as Linux, BSD, or Android, to run concurrently on big.LITTLE, Cortex-A53, and Cortex-A57-powered platforms. Furthermore, equipment manufacturers can leverage the SierraTEE SDK to add a Trusted Execution Environment to their ARM TrustZone-enabled 64-bit devices.

All most all next generation devices, from smartphones to microservers and headless residential gateways to 4G wireless infrastructure, will run on 64-bit ARM architectures. 64-bit computing overcomes the 4 GB memory barrier, enabling feature-rich, interactive applications such as gaming and high definition video display. As more and more devices move to 64-bit architectures, they will need to support important capabilities like virtualization and ARM TrustZone. Sierraware addresses this need by delivering high-performance, customizable hypervisor and TEE SDKs for 64-bit ARM silicon.

The SierraVisor Hypervisor for 64-bit ARM architectures:
  • Extends the life of applications by simulating the previous generation of hardware. Equipment vendors can swiftly migrate to new processors without porting existing software.
  • Allows legacy real time operating systems to run simultaneously with new open source platforms like Linux, BSD and Android.
  • Streamlines development by supporting SMP and AMP process management.
  • Secures sensitive data with a Trusted Execution Environment (TEE) available for every guest operating system.
SierraTEE for 64-bit ARM silicon allows devices to run a secure operating system and a normal, high-level operating system at the same time. SierraTEE protects confidential data like payment card data, DRM-protected content, and passwords from malicious attacks and malware. SierraTEE has been designed for a wide range of products that require trusted virtualization, such as set-top boxes, wireless and wired routers, mobile phones, and other consumer devices.

"As memory and processing requirements for embedded systems continue to grow, more and more hardware manufacturers will transition to 64-bit architectures," said Gopal Jayaraman, CEO of Sierraware. "SierraVisor and SierraTEE for 64-bit silicon are delivered as source code SDKs, enabling ARM-based hardware developers to customize the code over time to adapt to software and hardware changes."
