XScale Debug Support

Lauta, April 2006 - pls Programmierbare Logik & Systeme GmbH, a leading supplier of sophisticated debug tools for ARM7 and ARM9 processor derivates from various manufacturers, offers now a development environment for the XScale embedded processors.

The intuitive, configurable user interface of the UDE 1.13 supports the engineers with unrestricted C/C++-Support, a powerful symbolic browser, configurable toolbars, comprehensive context menus, as well as the capability to automate application specific windows with standard script languages and HTML.

Additionally multiple PXA255 and PXA27x specific features are implemented into UDE 1.13. The communication between debugger and target processor is realised via the JTAG Interface and a specific debug handler, which runs in the mini instruction cache of the XScale processors. The intelligent memory management ensures the proper function even of applications that changes dynamically exception vectors. Another advantage: Breakpoints - one for code and one for data - that are supported by hardware functions integrated into the PXA255 and PXA27x processors can be used easily and comfortable via the debuggers user interface optimized for that purpose.

The combination with the Universal Access Device (UAD) allows the realisation of a high speed JTAG communication with download rates of more than 1Mbyte/sec. This enables features like fast flash programming, simulated I/O, Linux kernel debugging, and short turn around times for the XScale processors in the design phase.
