SANTA BARBARA, Calif. Green Hills Software announced that the MFD-3068 Multi-Function Smart Display from CMC Electronics has received multiple Technical Standard Order (TSO) approvals to RTCA/DO-178C DAL A using the INTEGRITY-178 tuMP multicore real-time operating system (RTOS).
According to Green Hills, the multicore-based MFD-3068 is designed to be capable of driving up to four flight displays, including the primary flight display (PFD), and running multiple applications of mixed criticality up through the highest Design Assurance Level (DAL A).

The initial installation for the certified MFD-3068 multicore smart display is on a rotary-wing aircraft in Europe.
The MFD-3068 is the latest generation of displays from CMC. CMC’s MFD-3068 is engineered to offer high-performance multicore processing capability and a set of interfaces, including digital conversion, while supporting commercial serial interface standards as well as MIL-STD-1553. The MFD-3068 also provides video input and output ports.
