DDC-I HeartOS Real-Time Operating System

HeartOS, from DDC-I, is a lightweight real-time operating system (RTOS) with POSIX Profile 51 interfaces for mission-critical and safety-critical applications. HeartOS features a compact, lightweight deterministic TCP/IP stack and journaling file system. The stack was derived from the open source Light Weight TCP/IP (lwIP) stack and provides bounded real-time response for all algorithms. It is also highly scalable, supporting selective compilation for protocol options such as ARP, UDP, TCP, and ICMP. HeartOS is available immediately. Development seat pricing for HeartOS starts at $3,200/year.
