Why Choose Green Hills Software

We have the most reliable RTOS

Traditional real time operating systems from the 1980's, such as VxWorks and pSOS, can be crashed or subtly crippled by any tiny error in even the most insignificant part of your software. But during software development, our revolutionary INTEGRITY real time operating system detects nearly all of the bugs that would crash, lock up, or cause maddening random glitches in every other RTOS. Furthermore, INTEGRITY enables you to prevent any remaining bugs or viruses from crashing, locking up, glitching, or subtly crippling your system.

Our INTEGRITY-178B product is our INTEGRITY RTOS plus a complete off-the-shelf certification package for the Federal Aviation Administration's highest level safety standard: DO-178B Level A. INTEGRITY-178B is the only high reliability commercial RTOS that has been certified by the FAA to meet the FAA's highest reliability standard required for products that could potentially cause the catastrophic failure of an aircraft. INTEGRITY-178B has been selected to run the primary control systems of dozens of models of aircraft including the Lockheed Martin F-35 Joint Strike Fighter and Sikorsky's S-92 commercial helicopter.

INTEGRITY is far and away the world's most reliable RTOS.


We have the most productive software development environment
Our world leading MULTI software development environment is the most productive software development environment. MULTI slashes your time to market and your development cost by slashing your debugging time.
MULTI maximizes the reliability of your electronic product by rooting out bugs and glitches. MULTI also enables you to boost the performance and capability of your electronic product. The higher costs associated with using any other software development environment make MULTI the only embedded software development environment that you can afford.

We have the best optimizing compilers
According to the most respected embedded compiler benchmarks, the EEMBC benchmarks, our optimizing compilers generate faster and smaller code than any other embedded compilers. Faster and smaller code boosts the performance of your electronic product and reduces its memory and processor costs. The higher manufacturing costs associated with using any other embedded compiler makes our optimizing compilers the only embedded compilers that you can afford.

We slash your manufacturing cost
Our royalty-free µ-velOSity real-time microkernel, velOSity real-time operating system, and INTEGRITY real-time operating system are ideal for high volume products. In addition to saving money by avoiding royalties, you also save money because the small memory footprints of these RTOSes reduce the memory you need. The exceptional performance of these RTOSes also enables you to save money by buying a less expensive microprocessor.Our INTEGRITY RTOS provides a lower total manufacturing cost than any other high reliability RTOS.

Our MULTI software development environment also slashes your manufacturing cost. MULTI includes advanced memory usage analysis capabilities that enable you to reduce the memory used by your software. MULTI also enables you to maximize the performance of your software, enabling you to reduce your microprocessor costs.

Our customers love our products and our support

We encourage you to license our RTOS source code
The benefits of licensing RTOS source code far outweigh the costs. We are proud of the clean design and implementation of our RTOSes, so we are not afraid to disclose our RTOS source code to our customers.

We have the most advanced technology
INTEGRITY represents the most advanced RTOS technology. It is a breakthrough in RTOS security and reliability. MULTI is the most advanced technology for slashing software debugging time ever devised.
And our optimizing compilers have the most advanced code size and speed optimizations in the world. All of the most advanced embedded software development technology is available from us. There is no need to suffer the endless finger pointing inevitable in a multiple vendor solution. Competition is too intense for you to be held back by inferior software development technology.

We are the safest RTOS vendor
Losing your RTOS vendor could be very disruptive to your business, so choosing a stable RTOS vendor is critical to your success. In the last few years, half of the top ten RTOS companies have either gone out of business, been acquired, or abandoned the market. Many of the remaining RTOS vendors are in such financial difficulties that they may not survive much longer. Several of them have laid off more than half of their employees, including critical research, development, and support engineers.

In contrast, Green Hills Software has been a thriving embedded software business for the last twenty-five years: longer than any other embedded software vendor. We are far and away the most profitable embedded software vendor. We have made a profit in every one of the last 20 years. Over the last 20 years, we have grown an average of over 30% per year. We have the fastest growing RTOS market share, enabling us to become the second largest RTOS company
Green Hills Software is the only safe RTOS vendor.

We are dedicated to maximizing your return on investment
Wind River and the other royalty-bearing RTOS companies want your product to succeed in the market
so that they can extract the profit out of your product through their RTOS royalties

The Linux operating system is licensed under the GNU General Public License, which was designed by Richard Stallman (the copyright holder to much of the Linux software) to prevent you from making a profit off of his software. He thinks that making money from selling software is wrong!

By contrast, we don't think trying to make a profit is wrong and we won't take any of your profits.
Our products and services reduce your development costs by far more than you invest in them, making not only free, but by the time your product gets to market, you have already increased your profits. And since we don't charge any RTOS royalties, you get to keep all of the profits from manufacturing your product. In addition, we enable you to increase your profits further by getting you to market earlier, boosting your profit per unit, and increasing your unit sales.

No one is more dedicated to maximizing the reliability of your electronic product than Green Hills Software
