µ-velOSity, Royalty-free Microkernel RTOS (Real-Time Operating System) from Green Hills

Green Hills Software, Inc. released (April 4, 2006)  µ-velOSity, the youngest member of Green Hills’s INTEGRITY family. ROM footprint is only 1600 bytes and RAM footprint 1000 bytes. µ-velOSity also offers  application programming interface (API) and tools integration with the MULTI IDE enables embedded-system developers to create lower cost application and fast time to market.
 

µ-velOSity RTOS

David Kleidermacher, vice president of engineering at Green Hills Software:

Senior management teams have been asking us for not only the most technologically advanced and productive solution, but one that covers product families, product generations, and product verticals. µ-velOSity is an important part of our vision for a compatible technology that spans from the most deeply embedded, cost-sensitive devices to high-end, reliability-critical systems…

Fast Execution

µ-velOSity provides extremely fast services and real-time, deterministic execution – making it ideal for devices with demanding performance requirements. Context switching, service calls, and interrupt handling are finely tuned for maximum throughput and minimum latency, even under heavy loads. In addition, µ-velOSity boots extremely quickly – in less than 1500 processor cycles – making it ideal for consumer electronics and other devices that have an “instant-on” requirement.

Small Footprint

µ-velOSity’s footprint makes it ideal for embedded systems that have tight memory constraints.
µ-velOSity is delivered as a library and is automatically scaled down by the Green Hills tool chain to include only those services that are actually used by the developer’s application. The combination of efficiency in execution speed and footprint make µ-velOSity an ideal choice for power-sensitive devices.

Friendly Business Models

µ-velOSity is royalty-free, avoiding the headache of royalty reporting and making it ideal for high-volume, cost-sensitive embedded products. Green Hills Software also offers an extremely attractive business model for OEMs, enabling µ-velOSity to be included in a value-added solution for end product developers at a fraction of the cost of competing offerings.

Availability:

µ-velOSity is available for ARM, PowerPC, and ColdFire microprocessors, including ARM Cortex-M3, Cortex-R4, Atmel SAM7x and the ColdFire MCF5223. 

Jeff Bock, Global Product Marketing Manager, Freescale, Inc.

Green Hills Software’s µ-velOSity RTOS and the Freescale MCF5223x device family offer customers a compelling solution for lightweight, low-cost networking,” said Jeff Bock, 16/32-bit consumer and industrial product marketing manager for Freescale. “The MCF5223 adds a simple, cost-effective integrated Ethernet part to our popular ColdFire embedded microcontroller portfolio and µ-velOSity brings ultra-small code size, easy licensing and includes source code…
