Green Hills Software's INTEGRITY Operating System First to Be Certified under The IEEE and The Open Group POSIX Certification Program

"Green Hills Software recognizes the tremendous value that POSIX provides, both to our customers and to their customers," commented Dan O'Dowd, founder and CEO of Green Hills Software. "That is why we have taken a leadership position in the POSIX market. Nothing affirms this more than our being first with the latest certification -- a feat accomplished with the initial POSIX standard-conformant release of our INTEGRITY RTOS."

IEEE Std. 1003.1 System Interfaces

The IEEE Std. 1003.1 (POSIX.1) System Interfaces define a portable Application Programming Interface (API) to an operating system. There are more than 1,000 functions in the POSIX.1 System Interfaces, encompassing multitasking, inter-task communications, I/O, filesystem access, exception handling, timers, access control, and standard programming and math facilities. Application software written to adhere to the POSIX.1 System Interfaces can run on any computer with a conformant operating system, regardless of the operating system's underlying implementation or the computer's hardware architecture.

The use of POSIX.1 System Interfaces provides a number of significant cost- and time-saving benefits to purchasers of information technology (IT) and to software developers:

--IT purchasers gain the flexibility to procure systems from multiple vendors without incurring significant software migration costs. POSIX is particularly beneficial to organizations that want to spread purchases across multiple vendors or to award contracts to the lowest bidder, such as government organizations and automobile manufacturers.

--The use of POSIX.1 APIs allows organizations to leverage their investment in development across disparate projects that use different hardware and different conformant operating systems, spanning embedded and real-time systems, desktop computers and servers.

--The use of conformant operating systems allows developers to take advantage of third-party software components written to POSIX.1 APIs.

--POSIX interfaces are widely available on the UNIX(R) system and Linux, making them familiar to a large number of software developers and minimizing the learning curve associated with adopting a POSIX-conformant operating system.

POSIX Certification

The "POSIX: Certified by IEEE and The Open Group" program is the official program for certification to the IEEE POSIX standards. Certification allows operating system suppliers to substantiate claims of POSIX conformance based on defined test suites. There are more than 22,000 tests available for the 1003.1-2003 Base Product Standard, with approximately 17,800 tests in the test suite for the POSIX.1 System Interfaces. Certification also assures buyers that the products they specify and procure meet the standard and are warranted by the vendor to do so. "POSIX: Certified by IEEE and The Open Group" certification is widely supported and accepted by government and other major procurers of IT devices.

The INTEGRITY RTOS was certified on a Freescale MCP750-HA PowerPC processor. The certified version of the INTEGRITY RTOS is available now. The INTEGRITY RTOS will be certified on other platforms as required by its customers.

INTEGRITY customers with maintenance agreements can receive the certified version of the INTEGRITY RTOS at no charge. New development licenses for the royalty-free INTEGRITY RTOS start at $15,000.
