Plano, TX: Keil Software is pleased to announce simulation support for the Atmel AT91 ARM family of microcontrollers. The Keil µVision Debugger simulates the complete ARM instruction-set as well as the on-chip peripherals for each device in the AT91 ARM/Thumb microcontroller family. The integrated simulator provides complete peripheral simulation. Other new features in the µVision Debugger include:

• An integrated Software Logic Analyzer that measures I/O signals as well as program variables and helps developers create complex signal processing algorithms.
• An Execution Profiler that measures time spent in each function, source line, and assembler instruction. Now developers can find exactly where programs spend the most time.

"Using nothing more than the provided simulation support and debug scripts, developers can create a high-fidelity simulation of their actual target hardware and environment. No extra hardware or test equipment is required. The Logic Analyzer and Execution Profiler will help developers when it comes time to develop and tune signaling algorithms." said Jon Ward, President of Keil Software USA, Inc.

Atmel AT91 microcontrollers are based on the ARM7TDMI processor core and are targeted at low-power, real-time control applications. The microcontrollers have been successfully designed into Industrial Automation systems, MP-3/WMA players, data acquisition products, pagers, point-of-sale terminals, medical equipment, GPS, and networking systems.

Users who wish to give hardware-free simulation a try, may download the Keil ARM Evaluation Software from the Keil web site.
