Ashling's Development Tools for the NEXPERIATM DE200/50 iDTV Reference Design from NXP Semiconductors

Tools for NXP DE200/50 iDTV Reference Design

NXP Semiconductors offer a selection of Nexperia^TM Digital Extension (DE) 'add-ons' for analog TV sets to bridge the gap between analog and digital reception.  The NXP DE200/50 iDTV reference design provides a low cost, short time to market route for the introduction of new iDTV sets.  Based on the NXP Nexperia family of DTV solutions, the DE200/50 iDTV reference design allows digital video broadcast capabilities to be added to existing low-end and mid-end analog TV set designs.

Developed in co-operation with NXP Semiconductors, the Ashling toolset offers a comprehensive solution for NXP Nexperia MIPS application development.  The toolset includes

• Opella-XD or Vitra hardware emulators

• PathFinder Source-level Debugger

• GDB-Server-MIPS GNU GDB Server allows Ashling hardware emulators to be used with GNU GDB/Insight/Eclipse CDT and other 3rd party debuggers. Supported under Windows and Linux hosts.

PathFinder Source-level Debugger

PathFinder is Ashling's Source-level Debugger for Nexperia MIPS Home devices, with multiple user-configurable windows, point-and-click, drag-and-drop, hover data display, splitter windows, menu-bar, and script (macro)-file controls. PathFinder's Object-Oriented Monitoring and Editing System provides tree-structured "click to expand" access to all memory-areas, register sets, registers and bits of the NXP Nexperia^TM Home IC's core and co-processors, with a logical and friendly Windows-XP-style display.

PathFinder features include:

Ashling Emulators

Opella-XD (below)is the fastest available debug probe for embedded development on MIPS^TM RISC cores. Features a high-speed USB2.0 (480Mb/s) interface to host PC or Linux workstation  Opella-XD supports run-time control including program load, run, step, halt, hardware and software breakpoints and register/memory access.

Vitra is a powerful networked Emulator which can connect via Ethernet or USB and supports remote debugging via TCP/IP.  Vitra offers a full run-time control feature with Instruction and Data Trace and Triggering support via it's on-board high-speed acquisition hardware.

The Emulators are controlled via the PathFinder user interface and support:

• Program-load, run, step, halt, hardware and software breakpoints, register/memory display and modify and Source-level debugging via PathFinder
• High speed application code download
• Target connection via MIPS^TM-standard 14-way IDC connector
• Run/stop control of target application including go, halt, step over, step into and step out of
•  Full variable expression handling
•  Display/read/write of target system memory and peripheral registers
•  Support for all on-chip hardware breakpoints; unlimited number of software breakpoints.
•  Full cache support
• Target Reset control and Remote Reset detect
•  Support for big- and little-endian architectures
•  Full support for MIPS16^TM/MIPS16e^TM code compression
• Automatic sensing of target operating voltage.

GDB-Server-MIPS

GDB-Server-MIPS is a GNU GDB Server allowing Ashling hardware emulators to be used with GNU GDB debugger. Support is also provided for Insight, Eclipse CDT and MontaVista Devrocket Debuggers.  GNU GDB offers full run-time control support including start/stop program execution, breakpoints and memory read/write access via a console interface. Graphical interfaces are also supported (Insight, Eclipse CDT and MontaVista Devrocket).  The Ashling GNU GDB Server is available for Windows or Linux (x86 based) hosts.
