Green Hills Software Announces New Major Version
of µ-velOSity™
Real-Time Operating System
Adds Support for New Processors, File Systems and Device Connectivity
Solutions
 SANTA
BARBARA, CA—January 9, 2007—Green Hills Software, Inc.,
the technology leader in device software optimization (DSO) and real-time
operating systems (RTOS), today announced version 2.2, a major
new release of its µ-velOSity royalty-free
real-time operating system. Version 2.2 adds a PC-compatible file system,
wear-leveling and fault-tolerant flash device manager, USB 1.1 and
2.0 device class framework, and GHNet TCP/IP networking suite. These
new components are optimized for minimal footprint and maximum performance.
In addition, µ-velOSity 2.2 adds
support for the MIPS® processor
architecture.
“With the release of version 2.2, the µ-velOSity product
provides a comprehensive suite of middleware solutions that enable device
software developers to create full-functioned, network-enabled products
at the least cost and in the least amount of time, while meeting the
most stringent resource constraints of deeply embedded environments,” commented
David Kleidermacher, chief technology officer, Green Hills Software. “And
each of these new components is provided with the same business model
that has been so successful for the µ-velOSity kernel,
enabling both OEMs and end product makers to maximize their return on
investment.”
µ-File
The PC-compatible file system for µ-velOSity supports
popular FAT file formats and options and is portable to any device media,
such as IDE disk drives and Green Hills’ wear-leveling flash management
technology. µ-File is easy to use, with standardized programming
interfaces, including POSIX, C standard I/O, and C++ I/O streams.
µ-USB
The USB device management solution for µ-velOSity includes
a framework and application programming interface for managing USB device
connectivity. Details of USB protocol handling are performed by the software
so that developers can concentrate on application development. µ-USB
comes with implementations for a variety of device types, including mass
storage products such as USB memory sticks.
GHNet
The TCP/IP networking suite
for µ-velOSity includes a full range
of protocol support, including TCP, UDP, SNMP, and more. GHNet was designed
from the ground up for high-performance, small-footprint networking while
providing comprehensive RFC and standards compliance and validation.
GHNet is an ideal fit for resource-constrained devices where reliable
and efficient networking connectivity is a requirement.
MIPS
With the addition of support for MIPS, µ-velOSity now
supports all major 32-bit microprocessor architectures used in deeply
embedded devices. µ-velOSity supports
the MIPS32® architecture intended for high-performance, low-power,
system-on-a-chip (SOC) embedded applications.
About µ-velOSity
With a ROM footprint as small as 1600 bytes, RAM footprint as small as
1000 bytes, and service call times as low as 30 cycles, µ-velOSity is
ideal for the most resource-constrained embedded devices. In addition, µ-velOSity’s intuitive
application programming interface (API), world-class tools integration
with the MULTI IDE, and friendly
business models enable developers to create better performing systems
at a lower cost that get to market faster than development efforts
utilizing other RTOS offerings on the market today. In addition, the µ-velOSity API
is designed for upwards compatibility with the INTEGRITY real-time
operating system from Green Hills, providing an upgrade path for future
designs that may benefit from the additional reliability features of
INTEGRITY.
Availability and Pricing
µ-velOSity 2.2 is available today
for ARM®, Power Architecture®, ColdFire®, MIPS®, and
Blackfin® processor families.
