New RTOS on the block

Real time software is the heart of most complex, safety-critical embedded systems in military and aerospace applications. Many of these systems require software that is certified to development standards such as DO-178B “Software Considerations in Airborne Systems and Equipment Certification.” Operating systems from Wind River, Green Hills, and LynuxWorks are among the safety-critical software certified to various levels of DO-178. Joining this group, DDC-I just announced a new RTOS featuring bounded real-time response, time and space partitioning, patented slack scheduling, and claiming an easy path to DO-178B Level A certification. The memory-protected RTOS, known as Deos (DDC-I Embedded Operating system), is based on technology developed at Honeywell and deployed on dozens of commercial and military aircraft. You can read about the details of the Deos RTOS here. Development seat pricing for Deos starts at $5,700 per year. A second RTOS from DDC-I, a microkernel known as the HeartOS, targets general embedded as well as low- to mid-range safety-critical applications and will be available early next year.
