CAD-UL Announces First Debugging Tool for Intel XScale Microarchitecture; CAD-UL XDB Simulator Expedites Prototyping of Embedded Systems on New Microrchitecture.

Business/Technology Editors

MUNICH, Germany--(BUSINESS WIRE)--Nov. 21, 2000

CAD-UL, a market leader in embedded development tools for the Intel(R) 80x86 and Intel Pentium(R) families of microprocessors, today announced CAD-UL XDB Simulator for Intel XScale(TM) microarchitecture, the first software debugger for Intel's recently launched technology for Internet-capable wireless devices. CAD-UL XDB Simulator now supports the Intel 80200 Processor based on Intel XScale microarchitecture, speeding the development process by simulating the architecture of the Intel 80200 Processor on a host development platform. This allows engineers to debug application code, even at the lowest level, before their target hardware based on Intel XScale microarchitecture is ready.

"By extending our compilers and development tools to support the Intel XScale core, we will allow our customers to take advantage of a low-voltage, exceptionally fast microprocessor," said Martin A. Hermann, managing director of CAD-UL. "Engineers developing portable computing devices will now be able to prototype their application code for the Intel 80200 Processor based on Intel XScale microarchitecture with the greatest confidence, knowing that they are using a simulator-debugger that mirrors the exact architecture of the microprocessor itself."

"We are very pleased that CAD-UL's XDB debugger is now available for the Intel XScale microarchitecture family," said Michael Wall, director of Intel Server/Storage Operation. "It brings an ease of use, using a full-featured GUI that enhances the productivity of code debuggers and testers."

CAD-UL XDB Simulator for Intel XScale microarchitecture replicates the Intel 80200 Processor to provide integrated instruction-level debugging. Thus, XDB Simulator handles program functionality, including memory access and processor modes (32-bit and Thumb Mode), just as the microprocessor does--ensuring accuracy of debugging before prototype hardware is ready. XDB Simulator also supports all of the hardware features of the processor, including its on-chip coprocessors, to enable testing of (both) isolated modules and partial application code. This allows engineers to develop and test code specific to the Intel 80200 Processor, such as audio-processing algorithms, using the on-chip ACC0-DSP unit. In addition, CAD-UL XDB Simulator provides these additional features:

-- Support for Developers Working in a Team Environment--allows engineers to
collaborate on application and driver development, before target hardware is
available.

-- Coprocessor Support--simplifies testing of the complete embedded
application.

-- Interrupt and Exception Support--allows simulation to be handled according
to the processor's specification, or to be stopped manually, enabling engineers
to view the status and the exact location of each exception or interrupt.

-- 32-bit and Thumb Mode Support--provides simultaneous support, allowing
applications that are using these modes together to be executed and debugged.

-- Complete MMU Support--enables developers to access easily the paging unit of
the microprocessor as well as its protection features, easing the process of
incorporating MMU functionality into the application.

-- Manual and Automatic Memory Map Support--allows for manual or automatic
memory allocation through access to the discrete memory ranges of the
microprocessor, providing a higher degree of control over memory management.

-- Instruction Trace--allows developers to display a high-level language
C/C++/Assembler execution trace, making it easy to examine the history of an
executed program to find errors and understand the application's behavior.

-- GNU Compatibility--enables engineers to do all of their application
development with the standard GNU C/C++ compiler.

About the Intel XScale Microarchitecture

Intel XScale microarchitecture is the next generation of the Intel StrongARM microarchitecture. The Intel XScale microarchitecture was designed to optimize low power consumption and high-performance processing for a wide range of embedded Internet devices based on the same processor core, including handheld PCs and cell phones. Intel XScale microarchitecture is compliant with version 5TE of the ARM architecture.
