Opella-XD for the EMMATM Product Group from NEC Electronics

Opella-XD for NEC EMMA

The EMMA^TM LSI product group from NEC Electronics is designed for Digital AV applications, such as STB (Set-Top-Box), Digital TV, and DVD recorders.  The products deliver versatile and uncompromised performance through MPEG signal process core technology. EMMA^TM enables and empowers digital AV applications, from high-end requirements, such as digital High Definition (HD) signal process, to low-end requirements, such as one-chip processor for standard definition (SD) compatible devices.  Developed in co-operation with NEC, the Ashling toolset offers a comprehensive solution for EMMA^TM application development.  The toolset includes:

• Opella-XD Debug Probe
• 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 third party Debuggers. Supported under Windows and Linux hosts.

Opella-XD

Ashling's Opella-XD EJTAG Debug Probe is the fastest available debug probe for embedded development on MIPS^TM RISC cores.  Advanced features of Opella-XD include:

• Fast, easy-to-install USB 2.0 High-Speed Interface (480Mb/s) to host PC or Linux Workstation
• Unique auto-conditioning Probe provides maximum possible download speed to target with fastest JTAG clock frequencies
• Fast, trouble-free Plug-and-Play installation
• Small, versatile Target Probe Cable
• Fast in-target Flash Programming
• Works with Windows and Linux hosts
• Built-in diagnostics instantly show status of Target, Debug Probe and USB link
• Universal Hardware-Debug platform for all popular target architectures and compilers

Benefits of Opella-XD to the embedded hardware developer:

• Accelerates the entire embedded-hardware debug process: ultra-fast installation, code download and flash programming saves time at every code rebuild
• Instantly autoconfigures to target system
• Long-term investment: works with all popular target architectures and compilers
• Helps with the most difficult debugging tasks: hardware bring-up, operating-system booting, post-mortem debugging
• Future-proof: works with latest hardware-debug protocols, all popular host operating-systems
• Compact, easy-to-install target probe cables support all popular debug interfaces

Opella-XD Debug Probe Specification:

• Target EJTAG clock rates up to 100MHz
• Sustained code download to target at over 3MB/s (using 100MHz EJTAG clock)
• Supports all MIPS^TM hardware-debug standards: EJTAG 4.10, 3.10, 2.6x, 2.5x, 2.0x and 1.5x14-way or 20-way IDC target EJTAG connectors
• Configurable Target-Reset and Test-Port-Reset, under full user control
• Fine-grained adjustment of JTAG clock frequency from 1KHz to 100MHz
•  Supports target operating voltages from 0.9V to 3.6V. Opella-XD detects and automatically configures for the appropriate target voltages
• Supports RTCK adaptive clocking of debug data from target (EJTAG 4.10
• "Hot-plug" support; allows connection to a running target without resetting or halting
•  Fully powered by USB interface; no external power-supply needed
• Support for all on-chip hardware breakpoints; unlimited number of software breakpoints
•  Big-endian and little-endian target architectures supported
•  Full support for MIPS16^TM/MIPS16e^TM code compression

PathFinder Source-level Debugger:

PathFinder is Ashling's Source-level Debugger for the NEC Emma^TM family with multiple user-configurable windows 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 MIPS core, with a logical and friendly Windows-XP-style display.

PathFinder features include:

• Full C and assembly source level debug support including step-into, step-over and step-out-of
• Built-in Code Browser allowing rapid navigation of application source code
• Call Stack (Backtrace) window shows current function stack with optional parameter display
• Support for all third party MIPS^TM toolsets including MIPS^TM SDE, Green Hills Software, Wind River Systems (Diab Data), GNU GDB and all other ELF/DWARF compliant compilers 
• Powerful script language to control, monitor and log all Emulator functions from within PathFinder
• Remote Control Interface allows external applications to control PathFinder/Emulator via TCP/IP based API
• Operating System Debug using integrated RTOS monitoring window based on open-standard Kernel Debug Interface (KDI) API
• Full run-time control debug support for cached applications
• Hardware and unlimited software breakpoint support
• Translation Lookaside Buffer (TLB) window allowing easy setup and interrogation of the TLB
• Integrated flash programming and debug support
• Support for Windows 2000/XP/Vista

GDB-Server-MIPS: 

Ashling's GDB-Server-MIPS software package allows Ashling's Target Debug Probes to be used with the GNU GDB open-source debugger. The Ashling GNU GDB Server is available for Windows and Linux (x86 based) hosts and supports GNU GDB and all Eclipse CDT based debuggers.
