ANDOVER, Mass. – Mercury Systems Inc. in Andover, Mass., announced that its BuiltSAFE ROCK-2 safety-certifiableavionics subsystem is available pre-integrated with the Green Hills Software safe and secure INTEGRITY-178 tuMP (time-variant unified multiprocessing) real-time software operating system.

INTEGRITY-178 tuMP enables the full multi-core capabilities of the ROCK-2 subsystem in applications requiring DO-178C safety certification. The combined software and hardware solution is aligned with the Future Airborne Capability Environment (FACE) V2.1 technical standard.

The BuiltSAFE ROCK-2 avionics computer is a 3U OpenVPX subsystem pre-integrated with a choice of BuiltSAFE single-board computers with multi-core processors, avionics I/O, video processing, and software such as the BuiltSAFE graphics suite.

The ROCK-2 avionics computer is designed to enable different sections of the chassis to run at different design assurance levels (DAL) to facilitate a variety of technologies to augment the portion of the application that needs to run at highest safety level.

The choice of INTEGRITY-178 tuMP as the real-time operating system gives systems integrators deterministic low-level control over core affinity and use on the ROCK-2, compliant to CAST-32A.

The INTEGRITY-178 tuMP real-time operating system is for safety- and security-critical systems based on modern multi-core processors. INTEGRITY-178 tuMP improves flexibility in how the processor cores can be used.

The tuMP architecture has common OS controls the scheduling for of all processor cores and the overall communications between applications. INTEGRITY-178 tuMP supports the ARINC-653 interfaces and operating system capabilities necessary to align with the FACE V2.1 standard.

INTEGRITY-178 tuMP meets the ARINC-653 standard's requirement for multi-core operation as defined in Section 2 of Supplement 4 for the ARINC-653 standard.
