Green Hills Software Announces µ-velOSity for ARC 600 Core Family and the ARC Sound Subsystem

Ultra-small, Ultra-fast, Royalty-free Microkernel Ideal Fit for Performance-critical, Power-sensitive Applications

SANTA BARBARA, CA—September 2, 2008—Green Hills Software, Inc., the technology leader in device software optimization (DSO) and real-time operating systems (RTOS), today announced that µ-velOSity™ is now available for ARC® International’s ARC 600 Core Family of configurable cores and ARC Sound Subsystem. With a ROM footprint as small as 2K bytes, RAM footprint as small as 1K bytes, and service call times as low as 30 cycles, µ-velOSity is ideal for the cost-sensitive, high-performance applications for which ARC cores and subsystems are ideally suited.

µ-velOSity provides an important element in the software development infrastructure enabling the rapid development of software applications for the ARC 600 Core Family and ARC Sound Subsystem,” said Paul Holt, vice president, SoC product business unit at ARC International. “The µ-velOSity microkernel’s fast execution, tiny footprint, and world-class development tools integration enable ARC-based embedded systems developers to achieve faster time-to-market with lower development and production cost”.

Easy to Use
µ-velOSity is extremely easy to use. With complete kernel source code and the MULTI® integrated development environment’s kernel-aware debugging and project creation wizard, embedded software for the ARC 600 Core Family and ARC Sound Subsystem is easy to develop, analyze, debug, test, and optimize for any aspect of the system.

Fast Execution
µ-velOSity provides extremely fast operating system services and real-time, deterministic execution. Context switching, service calls, and interrupt handling for the ARC 600 and ARC Sound Subsystem are finely tuned for maximum throughput and minimum latency, even under heavy loads – making it ideal for devices with demanding performance requirements.

Small Footprint
The µ-velOSity microkernel’s industry-leading small footprint makes it ideal for embedded systems that have the tightest memory constraints. µ-velOSity is delivered as a library and is automatically configured by the Green Hills tool chain to include only those services that are actually used by the applications, delivering the smallest, most efficient footprint possible.

Simple Business Models
µ-velOSity does not have a per-unit royalty charge, avoiding the headache of royalty reporting and making it ideal for high-volume, cost-sensitive ARC-based embedded products. Green Hills Software’s attractive licensing models enable µ-velOSity to be included in a value-added solution for end product developers at a fraction of the cost of other offerings.

“The ARC 600 Core Family and ARC Sound Subsystem present an ideal architecture for Green Hills Software’s µ-velOSity real-time operating system which specializes in top performance, ease of use, and small memory and power footprint,” commented David Kleidermacher, chief technology officer of Green Hills Software. “On top of all of this, Green Hills offers royalty-free, simple business models which are critical to those employing ARC in high-volume electronic products.”
