Green Hills Software

Green Hills Family of RTOSes

Green Hills Software family of real-time operating systems is comprised of INTEGRITY

velOSity and u-velOSity. The family represents a continuum of real-time operating systems

featuring common communication protocols, common development tools and a 100% upward

compatible programming interface (API).

INTEGRITY

Real-Time Operating System

INTEGRITY is a secure, royalty-free real-time operating system intended for use in embedded

systems that require maximum reliability. INTEGRITY represents the most advanced RTOS

technology on the market today.

INTEGRITY uses hardware memory protection on the i.MX applications processor to isolate and

protect itself and user tasks from incorrect operation caused by accidental errors or malicious

tampering. Its object-oriented design allows strict access control and verification of the security

and integrity of data, communications, individual components, and the system as a whole. Unlike

other memory protected operating systems, INTEGRITY does not sacrifice real-time performance

for security and protection. It is first and foremost a true hard real-time operating system.

INTEGRITY’s special features include:

• Guaranteed resource

(CPU and memory) availability

• Fast, deterministic real-time response

• Virtual device drivers

• Proven certification history for DO-178B

Level A, IEC61508 SIL3, POSIX, FDA

•

Unified platforms for aerospace and defense,

automotive, industrial safety, medical,

software-defined radio and wireless

velOSity Real-Time Operating System

The velOSity™ Real-Time Operating System (RTOS) is small, fast and royalty free, making it a

perfect fit for cost-sensitive, high-volume and resource constrained embedded applications.

velOSity offers developers a rich set of kernel services, device drivers, BSPs and middleware.

In contrast to INTEGRITY, the velOSity RTOS is configured to run in flat memory models,

optimizing both its footprint and execution speed. It can also be configured for use without a

board support package for your target hardware, further reducing your memory footprint and

implementation complexity.

u-velOSity Real-Time Microkernel

The µ-velOSity real-time microkernel is the smallest of Green Hills Software’s family of

royalty-free operating systems. It is implemented as a C library so it can be easily ported

to a number of target architectures. Its simple design as well as integration with the

best-in-class MULTI tools make µ-velOSity both easy to learn and simple to use.
