IAR J-Trace, JTAG+ Trace for Cortex-M3

J-Trace

AR J-Trace for ARM Cortex-M3 is a high speed hardware trace probe developed from ground-up for ARM Cortex-M3; it connects via USB to the PC host running Windows. IAR J-Trace integrates seamlessly into IAR Embedded Workbench and is fully plug-and-play compatible, and in addition very easy to use.

 

IAR J-Trace combines an embedded trace macrocell (ETM) with an embedded in circuit emulator (ICE) macrocell to deliver all the real-time debug functions of a traditional emulator. It has a 4MB buffer memory. No special hardware is required to substitute for the real microprocessor functions in order to make them visible.

 

Other features include full integration with the C-SPY debugger, J-TAG speed up to 20MHz and trace speed up to 200MHz.
