Linux support for Altera's Nios II

1 April 2009 Design Automation

Wind River has announced the availability of Linux support for Altera’s Nios II embedded processor. Embedded developers deploying products based on the Nios II processor can use this Linux solution across Altera’s entire portfolio of FPGAs and HardCopy ASICs.

Wind River’s Linux solution for the Nios II processor is based on Linux 2.6 kernel technology, the GNU 4 tool chain and the Eclipse-based Wind River Workbench Development Suite. This solution adheres to well-known industry standards on Linux and tools and is customised to support the Nios II instruction set, the processor architecture and the custom instructions feature that can be implemented in the FPGA fabric to increase system performance.

Providing software developers a fast start on an FPGA-based platform, the Altera and Wind River development framework offers an integrated, network-enabled processor-system reference design that boots Linux on power-up. Implemented on a Cyclone III FPGA development kit, the underlying hardware platform is a fully timing-constrained and performance-optimised processor subsystem design with a Nios II/f core and a number of common system peripherals such as Ethernet, timer and UART. A matching board support package (BSP) and a pre-built Linux kernel for this hardware platform give application developers a familiar and stable environment to jumpstart their application development effort. The same processor system reference design can target any FPGA or HardCopy ASIC in Altera’s product portfolio.
