µVision Simulates Atmel AT91SAM7Sxx Devices

Plano, TX: Keil Software has extended Atmel AT91 device simulation support to include the new AT91SAM7Sxx microcontroller devices. The Keil µVision Debugger simulates the complete ARM instruction-set as well as the on-chip peripherals for each device in the AT91SAM7Sxx ARM/Thumb microcontroller family.

"Accurate device simulation has serious benefits when compared to debugging solutions that rely only on the ARM Embedded ICE," said Reinhard Keil, President, Keil Elektronik GmbH. "The µVision Simulator provides unlimited breakpoints and allows timing analysis of software algorithms. This is essential for software debugging of single-chip designs or hardware with only Flash memory. The Embedded ICE has limited capabilities on such systems," continued Mr. Keil.

The Keil Development Suite for ARM provides everything you need to develop Atmel AT91SAM7Sxx Microcontroller applications:

• Startup code with device-specific configuration, example projects, and pre-configured programming algorithms for the Keil ULINK USB-JTAG Adapter are included.
• The Keil CARM C Compiler (included in the PK-ARM and CA-ARM kits) is optimized for the ARM Thumb instruction mode (which offers a 30% code size reduction compared to ARM native mode). The C run-time library, which is coded primarily using Thumb mode, helps the CARM Compiler generate extremely tight program code—an important consideration when using single-chip AT91SAM7Sxx devices.
• The PK-ARM Professional Developer's Kit includes the Advanced RTX Real-Time Kernel making this suite a truly complete development system for ARM-based microcontrollers.

The Atmel AT91SAM7S Flash microcontroller series, based on the ARM7TDMI core, bridges the gap between 8/16-bit and 32-bit applications. These single-chip devices integrate a rich peripheral set including a watchdog clocked by an on-chip RC oscillator, power supply monitors and hardware protection of Flash memory.

"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 help developers create and tune signaling algorithms," said Jon Ward, President of Keil Software, Inc.

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