SUNNYVALE, CA—March 8, 1999—Real-Time Innovations, Inc. and Wind River Systems (NASDAQ: WIND) today announced the availability of RTI PerformancePak(tm).
Real-time embedded systems must be fast and reliable. ScopeProfile is a graphical execution profiler that helps Tornado(tm) developers get the highest performance out of their embedded processor. MemScope is a graphical memory analyzer that helps control memory usage and increase reliability of an embedded application. Together, the PerformancePak tools form a powerful toolkit with overwhelming value.
Stan Schneider, President of Real-Time Innovations, said, "Visualization is an amazingly powerful capability and visualization tools let the developer see what an application is doing, understand it, and make it work. The PerformancePak tools are critical for any programmer concerned about execution speed or long-term reliability."
Avi Schlank, Director of Product Marketing for Wind River Systems added, "StethoScope(tm) is one of our most popular WindPower(tm) tools. With the release of the complementary PerformancePak, RTI has delivered two additional tools that will benefit all our customers. Now, Tornado developers can tune their applications for top performance to ensure that they will run flawlessly in the field. PerformancePak helps make Tornado the highest-performance, most-reliable real-time development environment on the market."
Pak PerformancePak includes the ScopeProfile execution profiler and the MemScope memory analysis tool. Both feature intuitive graphical interfaces, and are intimately integrated into the Tornado development environment.
ScopeProfile helps Tornado developers get the top performance that is critical for real-time systems. ScopeProfile's dynamic display shows exactly where a program is spending time, whether in the code or the operating system. It gives a full, accurate tree profile with no special compilation or hardware. ScopeProfile enables developers to see where the CPU is spending its cycles, understand performance bottlenecks, and make it run fast.
Combined with RTI's StethoScope graphical data monitor, ScopeProfile can also display dynamic execution loads. This lets developers quickly isolate bottleneck functions during transient conditions. Dynamic profiling is the key to top performance.
MemScope helps developers ship reliable products. Since real-time programs execute with limited resources for long periods, they must use memory carefully. Memory "leaks" - the gradual loss of small memory blocks - will eventually cause failure. MemScope graphically analyzes memory usage in a running Tornado program and provides a live summary of each allocated block in the system, including a full call-stack history of each memory allocation. MemScope lets Tornado developers see memory leaks, understand memory usage, and use memory efficiently and safely.
Available for UNIX, Windows 95, and Windows NT host platforms and more than 20 target processor families, Tornado is the industry's most comprehensive development environment for embedded systems. Tornado seamlessly integrates the industry's most powerful development tools and VxWorks(r), a feature-rich, high performance and scalable real-time operating system.
Completely open and customizable, Tornado also facilitates the use of third-party and custom-developed tools to enhance its capabilities and meet unique customer requirements. Tornado has more than 280 software and hardware partners and is used by thousands of developers worldwide.
RTI PerformancePak for Tornado is currently available for most Tornado configurations. Interested customers can get more information by calling Wind River Systems at 800-545-WIND or 510-748-4100, calling Real-Time Innovations at (408) 720-8312, or visiting www.wrs.com or www.rti.com.
