DDC-I, Inc. is a software development company providing real-time operating systems, software development tools and software services for safety critical embedded applications. Headquartered in Phoenix, Arizona, DDC-I is a privately held corporation.


Founded in 1980, DDC-I is a provider of complex COTS and custom embedded solutions. The first product released in 1985 was a development toolset for Ada. Support for mixed language development was added in 2000 with the addition of C & Embedded C++ programming languages. The company was an early contributor to the Ada standard as well as contributors to the Java “Expert Group”[1] for Safety Critical Java. In November 2008 the company entered the embedded real-time operating systems (RTOS) market[2][3] with its products, Deos and HeartOS, based on underlying software technology originated at Honeywell International Inc.[4]

In 1997 the company was awarded a joint contract with Sikorsky Aircraft and Boeing Defense & Space Group's Helicopters Division to develop software to be used in the Boeing/Sikorsky RAH-66 Comanche.[5]


  • Deos is a time and space partitioned real-time operating system (RTOS) that was first certified to DO-178B level A in 1998. Deos contains several patented architectural features including enhancements for processor utilization and binary software reuse. Deos users have the ability to add on optional ARINC-653 personality modules designed to fit different application needs. Deos supports the PowerPC, x86 and Mips architectures[6][7] and was selected as one of the Hot 100 Electronic Products of 2009 by EDN Magazine.[8]
  • HeartOS is a POSIX-based hard real-time operating system that has been designed for small to medium embedded applications including safety critical applications. HeartOS operates on x86, PowerPC, ARM[9] and other 16-bit and 32-bit processors. It is configurable without the POSIX interface layer for memory-constrained systems.
  • OpenArbor is an Eclipse-based integrated development environment for C, Embedded C++, and Ada application development.
