Description

The Nucleus PLUS operating system from Mentor Graphics is available for Tensilica's Diamond Standard and Xtensa processor product lines.

Tensilica's Nucleus OSKit porting environment is a powerful tool based on a technology innovation that automates the configuration of the Nucleus PLUS kernel so that it matches and runs "out of the box" on the Xtensa or Diamond processor. It provides an integrated interface between the processor and Nucleus PLUS.

Nucleus Plus is distributed in source code form by Mentor and uses the compile-time HAL to obtain all necessary processor configuration information.

BSP for ISS and XT2000

Nucleus PLUS Board Support Packages are also generated for the application optimized Xtensa processor. The Instruction Set Simulator BSP facilitates early software development and the XT2000 BSP enables hardware verification on the CPLD-based evaluation board. Debug is accomplished through the On Chip Debug (OCD) block with support on NT and Solaris-based hosts. The BSP will support full Nucleus PLUS functionality including any new instructions that have been defined by the designer.

Nucleus Embedded Software Support

Mentor Graphics provides a full suite of application software to support users of its Nucleus operating system, including software for networking, GUI, file system, USB, bus, and security.

Mentor's networking offerings include Ethernet, gigabit, and wireless communication. 53 networking protocols form the basis for common implementations, and include:

• IPv4/IPv6 for present and future communications
• VPN for a secure, remote network connection
• Secure wireless to keep prying eyes out of your customer's data stream
• Web services and secure Web services including HTTP, FTP, SSH and more
• Management through SNMP
• Gateway services for residential use

The graphics components of the Nucleus OS simplify the development of high quality user interfaces with modular services that handle the details of hardware support, rendering, windowing and more.

The Nucleus OS provides file system products while keeping the complexity of this work hidden behind a simple, extensible API.

The Nucleus OS offers a full line of USB software to overcome the USB requirement. This software ranges from hardware drivers to stacks, to class drivers, to multimedia management.

The Nucleus OS provides support for an array of bus-based systems. These are used to control peripherals on a single platform, or to coordinate with controllers in separate devices.

The Nucleus OS strives to stay ahead of the digital thugs by providing top-of-the-line encryption, data hashing, and peer certification software.
