System Navigator™ EJTAG Probe plus iFlowtrace™
EJTAG Probe featuring iFlowtrace™ Trace System for M4K Microcontrollers

The System Navigator™ EJTAG Probe plus iFlowtrace consists of the System Navigator EJTAG probe with instruction trace support for MIPS-based® cores that are enabled with iFlowtrace. iFlowtrace (Instruction Flow Trace) technology is an option on the MIPS M4K® core that allows tracing of all executed M4K instructions while minimizing on chip resources and pin requirements, especially critical for microcontroller designs. A high degree of compression is used to reduce bandwidth to capture all program execution flow and maintain high throughput. The iFlowtrace physical trace port has one double data rate (DDR) clock and 4 data lines.

The FS2 System Navigator EJTAG plus iFlowtrace probe has a single connector on the probe end and a split cable on the target end with two connectors - the standard 14-pin EJTAG connector and a 10-pin iFlowtrace connector. The EJTAG connector is plugged into the standard dual-row 14-pin header on the user’s target board, providing complete run control of the M4K core. The iFlowtrace connector connects to a matching 5 x 2 pin header on the user’s target board that carries the clock and four data trace signals to the probe for storage.

Extensive debugger support including Eclipse-based Navigator IDE Debugger on Windows and Linux

Software development tools used with the System Navigator probes include the GNU-based MIPS SDE toolchain and the new MIPS Navigator™ IDE debugger. All the probe features are available from the Navigator IDE interface which has an Eclipse-standard interface and CDT components with special plug-ins for processor debugging using the probe.

The System Navigator probes are also supported by the Viosoft embedded Linux Arriba debugger and Mentor Graphics Embedded Nucleus EDGE debugger. Now you can use the System Navigator probe with the best-in-class software tools for an intuitive, easy to use interface. The system runs on a PC with Windows®NT/2000/XP or RedHat Linux and requires a USB 2.0 or 10/100 Ethernet connection (optional).
