| Dear Customer, |
Developer's Toolbox remains one of the most popular sections at www.iar.com. This month you'll find an article about priority inversion, a problem that can lead to reduced system responsiveness.
As part of the company's 25th anniversary we have previously published an interview with the founder of IAR Systems. This month Nadim Shehayed, General Manager of IAR Systems in the US, reveals some details from 1993 when he started our California office.
We want to share our experience and our stories with you. Maybe you have something that you would like to share with us?
Best regards,
Margareta Eriksson Hoerling
Marketing Communications Manager

| Priority inversion |
In systems where different tasks need exclusive access to a resource, priority inversion can occur. This is a phenomenon where a low priority task gets to run and starts to use a resource with exclusive access. If a higher priority task needs the same resource it halts until the low priority task has released the resource. This would effectively give the high priority task a priority level beneath the low priority task. Should medium priority tasks try to run, they can run as if they have a higher priority than the high priority task. This is called priority inversion.

| Odd circumstances called for creative measures entering the US market |
When IAR Systems started its first local office in the USA the compiler had an error message suggesting that the user contacted “Uppsala” for technical support. US customers called their local IAR Systems office confused about U-P-P-S-A-L-A.
Nadim Shehayed, Area Manager in the west coast office was the person actually establishing the first IAR Systems office in the USA. He remembers dealing with the customers calling, confused about the strangely spelled and in general unfamiliar concept of “Uppsala”.
“I said that it’s a special error code. Don’t worry about it. It’s something we put in there to know where it happened.”
