Green Hills Software Expands Benefits of -velOSity to More Markets Served by Freescale

Small, Fast, Easy-to-use, Royalty-free RTOS Now Available for all 32-bit Freescale Processors based on Power Architecture™, ColdFire® or ARM® Technology
July 26, 2006
—Green Hills Software, Inc., the technology leader in device software optimization (DSO) and real-time operating systems (RTOS), today announced its µ-velOSity royalty-free real-time operating system has expanded its support of Freescale processor families, thereby extending the benefits of µ-velOSity into more markets, such as automotive, networked appliances and consumer electronics. Freescale processor families added to the µ-velOSity offering include the MPC555x, MPC85xx, ColdFire MCF54xx, i.MX31 and MAC71xx. This expanded support enables developers to deploy a wider range of products based on the most technologically advanced microkernel designed for resource-constrained, performance-critical, and cost-sensitive embedded systems.

“With its highly optimized footprint and execution speed, µ-velOSity is an excellent fit for performance-critical embedded products based on Freescale’s 32-bit processors and microcontrollers,” said Lynelle McKay, vice president and general manager of Freescale’s Digital Systems Division.

Business Model

Many of Freescale’s 32-bit processors and microcontrollers target high-volume, cost-sensitive markets such as consumer electronics and automotive. With its royalty-free and friendly OEM business model, µ-velOSity is well-suited to such target markets, enabling device makers to achieve a significantly lower production cost than is possible with competing offerings that require per-unit or large up-front runtime license charges. In addition, the tools integration with Green Hills’ MULTI IDE, TimeMachine tool suite, optimizing compilers, and debug probes enable developers to create a more reliable product while bringing it to market sooner.

“We are very pleased with the partnership that has developed over the years between Green Hills and Freescale,” commented David Kleidermacher, CTO of Green Hills. “Green Hills helps Freescale develop next-generation devices by utilizing our knowledge and experience relating to 32- and 64-bit microprocessor technology. Correspondingly, Freescale helps us to ensure that availability of our operating systems and tools precede silicon availability, giving our mutual customers a head start on their designs.”

Optimized for Freescale Cores

µ-velOSity’s most performance-critical operations, such as context switching, interrupt handling, and system call servicing, are finely optimized by a combination of the world’s best ARM, ColdFire, and Power Architecture compilers and painstaking hand-coding of a small number of assembly code sequences. The result is a real-time kernel with industry-leading performance in terms of execution throughput and response time. Yet with ROM and RAM footprints as small as 1600 and 1000 bytes, respectively, µ-velOSity frees device makers to employ their precious memory resources for more and better application-level functionality.


The Green Hills µ-velOSity real-time operating system is available today for Freescale’s processors built on Power Architecture technology, ColdFire microcontrollers and applications processors based on ARM cores.
