Express Logic`s StackX Selected Best of Show by eg3.com for ESC 2009

New tool identifies maximum stack usage, ending guesswork and stack overflow
SAN DIEGO--(Business Wire)--
Express Logic, Inc., the worldwide leader in royalty-free real-time operating
systems (RTOS), today announced that its new StackX development tool was
selected by eg3.com as "Best of Show" at this year`s Embedded Systems Conference
(ESC) in San Jose. Each year, eg3.com selects a small number of new products at
major industry conferences such as ESC, and names them Best of Show. Last year,
Express Logic`s BenchX Eclipse-based IDE won an Editor`s Tech Choice award from
eg3.com. This year, StackX garnered a Best Of Show selection.

"Express Logic`s new StackX tool enables developers to avoid stack overflow in
embedded systems," stated Jason McDonald, President of eg3.com. "We awarded it
Best of Show because stack overflows are omnipresent problem in many embedded
software designs. What`s cool about StackX is that it performs a comprehensive
analysis of a complete application at the executable code level, computing the
worst case stack usage the application can experience."

StackX is a new development tool that helps embedded developers avoid stack
overflow problems that traditionally have plagued embedded systems, while at the
same time avoiding overly cautious memory allocation for the stack, which wastes
precious system resources. StackX performs a comprehensive static analysis of a
complete application at the executable code level, computing the worst-case
stack usage the application can experience. Express Logic is the only RTOS
company that can tell its customers how large a stack they need for each
application thread.

Notably, stack overflows have challenged embedded system design for many years.
Industry commentator Jack Ganssle has observed:

"With experience, one learns the standard, scientific way to compute the proper
size for a stack: Pick a size at random and hope."

-- Jack Ganssle, "The Art of Designing Embedded Systems," Elsevier, 1999.

After seeing StackX at ESC, Ganssle commented, "Express Logic (makers of the
ThreadX RTOS) had a huge booth where they demonstrated the latest in their
X-series of products: StackX. StackX analyzes your .elf file and computes
exactly how much stack space your application will require. There are some
limitations, of course. It can't handle recursion or a few other oddball
techniques. But StackX does change the standard way off calculating stack size
(take a wild guess and sacrifice a goat) to nearly a science."

Jim Turley, editor of Embedded Technology Journal, added his enthusiasm for
StackX, commenting, "So let us heap praise on StackX for its ability to quantify
a hitherto informal process. Any tool that improves code reliability is a good
thing. If it decreases programmer frustration, so much the better. A
well-proportioned stack is a thing of beauty, and StackX provides a way for
interested programmers to stay abreast of their memory requirements. "

"We greatly appreciate eg3.com`s award for StackX as Best Of Show, and we`re
proud to have earned their praise," commented William E. Lamie, president of
Express Logic. "StackX joins our award-winning BenchX IDE, and our new TraceX V5
analyzer as we continue to expand our tools offerings to better serve the needs
of embedded software developers."

Shipping and Availability

StackX is available from Express Logic at a price of $1,000 per developer for a
perpetual license.
