Tanto PortTrace with ETM7 Support

The Tanto PortTrace for ARM module is an extension module to the Tanto for ARM base module. This extension module enables real-time trace capture for all ARM based target systems with Embedded Trace Macrocell ( ETM7 ). An ARM specific adapter module (Cable-Driver with Port Link module) connects to the standard Mictor connector of the target trace port.
The trace information allows advanced real-time debugging with filtering capabilities for the program flow and for data analysis.

The following list summarizes some of the technical features

• Support of the Embedded Trace Macrocell (ETM7 and ETM9)
  - with CPU clocks up to 250 MHz
  - with normal and half-rate clock modes
  - with 4- and 8-bit trace port width
• Trace memory for up to 2 million CPU cycles
• Support within HiTOP5 IDE for ETM setup and trace display
• Support of ARM ETM trace capabilities with
  - 2 data comparators
  - 4 address comparators
  - 2 counters
• Configurable trace information
  - for instruction trace filtering
  - for data trace filtering
  - with time stamp information (7.5ns resolution)
• Display of trace information in own window with linking to High Level Language source window
• Forward and backward stepping in trace data

Target Interface Description for ARM® JTAG and ETM7

Tantino for ARM
Start your ARM7 or ARM9 project using this compact and cost-effective debug interface. All run-control debug facilities like breakpoints, watchpoints, single-step, register and memory view are supported. Together with the HiTOP5 IDE, a Windows based environment, you have everything to compile and debug your application including RTOS support.

The following list summarizes the technical details:

• Supports ARM7™, ARM9™ and ARM9E™ processor cores (XScale in preparation) with EmbeddedICE™ debug logic
• JTAG interface for connection to the target system supporting target voltages from 1.8 - 5.0V and JTAG clocks up to 30MHz
• USB1.1 interface for connection to PC host
• No external power supply required (USB powered)
• Run-control facilities: run / halt, single step / line step, breakpoints and watchpoints
• and much more...
