Embedded Linux 2.6 and GNU tools based on GCC 4.2, both available at www.linux-xtensa.org, is backed by two well-respected Linux industry partners. Embedded Alley Solutions, Inc. of San Jose, CA, provides Platform Optimized Linux Solutions, Linux consulting services and training. Timesys, of Pittsburgh, PA, is providing subscriptions to LinuxLink for Tensilica customers to access embedded software, tools, documentation, and support and Timestorm: an Eclipse-based IDE that provides a point-and-click interface for kernel and root filesystem configuration, profiling, testing, and debugging.

Open-source Linux is the target operating system for Tensilica’s Diamond Standard 232L processor, the industry’s smallest, lowest power licensable 32-bit core that supports the Linux operating system. The Diamond Standard 232L includes a Memory Management Unit (MMU) for Linux support. In addition, with Xtensa configurable processors, memory management options include region protection, region protection with translation, and an MMU with Translation Look Aside Buffers (TLBs), including no-execute bit security support for the Linux operating system.
