San Francisco, CA—Green Hills Software Inc. announced at “electronicaUSA with the Embedded Systems Conference (ESC) 2004, Mar. 29-April 1 at the Moscone Convention Center, that its velOSity real-time microkernel, the foundation of its Integrity real-time operating system (RTOS), is now available independently.


San Francisco, CA— Green Hills Software Inc. announced at “ electronicaUSA with the Embedded Systems Conference (ESC) 2004, Mar. 29-April1 at the Moscone Convention Center that its velOSity real-time microkernel, the foundation of its Integrity real-time operating system (RTOS), is now available independently.

Shipping for more thanmicrokernel requires as little as 3 KB of RAM and uses an architecture that never disables interrupts in systems calls, guaranteeing the fastest possible interrupt response times across all microprocessors.

'With the release of the velOSity microkernel, Green Hills is uniquely positioned to satisfy the entire spectrum of 32- and 64-bit embedded applications, from the smallest, high-volume, resource-constrained consumer applications through the largest, most mission-critical avionics, defense and telecommunications systems,' says Dan O'Dowd, Green Hills’ founder and CEO. “This provides large organizations with a single, fully interoperable embedded software development solution that satisfies their requirements across all projects.”

velOSity microkernel enables fast application development out of the box, and is tightly integrated with the Multi Integrated Development Environment (IDE), the industry's market-leading development tool set, and the Green Hills Optimizing C and C++ compilers. This combination provides a completely turnkey solution that allows developers to be instantly productive. velOSity is so intuitive that developers can be up and running in minutes. Moreover, velOSity runs on custom hardware without any porting or customization required. velOSity is completely hardware independent and doesn’t need a board support package (BSP) or any other board-specific code.

In addition, velOSity inherits all of Integrity’s device drivers, BSPs and middleware. This allows velOSity developers to use many runtime components, including file system support, USB, CAN, Bluetooth, IPv4, IPv6, SSL, Web server, CORBA and graphics. While a BSP is op-tional with the velOSity architecture, developers can take advantage of a rich library of more than 100 BSPs and device drivers available for the Integrity RTOS without having to make any modifications.

Both the velOSity microkernel and Integrity RTOS also use the same application programming interfaces, including POSIX system interfaces and adaptation layers for VxWorks, pSOS and other legacy RTOSes. Software developed for the velOSity microkernel is 100% upwards compatible with Integrity RTOS. This provides a seamless migration path for velOSity users that want to upgrade to the reliability and security features, such as memory protection and secure partitioning, offered by the Integrity RTOS.
