DDC-I has released its safety-critical, DO-178B Level A certifiable, HeartOS real-time operating system and OpenArbor development tool suite is available for the ARM7 and ARM9 families of processors. The HeartOS running atop ARM processors provides a scalable, low-power, high-performance computing platform for developing and hosting mission- and safety-critical applications for the avionics, transportation, industrial automation, and medical markets. HeartOS is particularly well suited for applications requiring DO-178B certification from the FAA and international aviation authorities.

HeartOS is a lightweight, deterministic kernel that utilizes POSIX profile 51 interfaces as well as profile 52 features such as socket communications. Currently undergoing certification to DO-178B Level A, the HeartOS kernel provides POSIX scheduling, threads, semaphores, mutexes, barriers, condition variables, message queues, clocks and timers. HeartOS is highly scalable and configurable, making it ideal for 16- and 32-bit microcontrollers and microprocessors. HeartOS also features a compact, lightweight deterministic TCP/IP stack for embedded networking and internet connectivity.

Development support for the HeartOS includes DDC-I's Eclipse-based, mixed-language OpenArbor IDE, which features C and C++ optimizing compilers, a color-coded source editor, project management support, automated build utilities, and a mixed-language, multiwindow, symbolic debugger.
