Green Hills Software, Inc. is the technology leader in device software optimization (DSO) and real-time operating systems (RTOS)for 32-bit and 64-bit embedded systems. Green Hills Software provides a family of operating system products including the µ-velOSity real-time microkernel, the velOSity RTOS and the advanced INTEGRITY RTOS. This family of operating systems provides developers with a seamless migration path for future designs that grow in complexity and requirements. In addition, Green Hills Software has integrated its MULTI and AdaMULTI integrated development environments and optimizing compilers with other leading embedded operating systems.

Green Hills Software's MULTI and AdaMULTI integrated development environments enable manufacturers to reduce development costs and increase productivity by empowering developers with a common development platform that includes the most powerful and complete set of tools for optimizing software time-to-market, reliability, performance and manufacturing cost.

Green Hills Software was founded in 1982, is privately held, has been profitable since its inception, and is growing at an average rate of 30% per year. Green Hills Software is now the world's #2 RTOS company. Green Hills Software is headquartered in Santa Barbara, California with European headquarters in the United Kingdom.

RTOS

The µ-velOSity real-time microkernel is the smallest of Green Hills Software's family of royalty free operating systems. Its simple design and integration with the best in-class MULTI IDE make ì-velOSity both easy to learn and simple to use. ì-velOSity is ideal for use in the most resource-constrained embedded devices.

The velOSity RTOS is small, fast and royalty-free-making it perfect for high volume, cost-sensitive, and deeply embedded applications. The velOSity RTOS is integrated with Green Hills Software's best-in-class MULTI embedded software tools and provides a rich set of kernel services, device drivers, BSPs and middleware.

The INTEGRITY RTOS is a secure, maximum reliability, royalty-free real-time operating system intended for use in mission critical embedded systems. The INTEGRITY RTOS uses hardware memory protection to isolate and protect itself and user tasks from incorrect operation caused by accidental errors or malicious tampering.
