ETM and ETB Trace for ARM7 and ARM9<br />

The ARM7 and ARM9 ETM trace board is an add-on for the Universal Access Device 2+ and allows<br />

the recording of trace information of a running program on the ARM derivatives in real-time.<br />

UAD ARM7 and ARM9 ETM Trace Add-On Board<br />

The system is an optimized solution to support all the features of the ARM ETM trace port<br />

functionality in the best manner.<br />

<br />

<br />

<br />

<br />

<br />

<br />

<br />

<br />

<br />

<br />

Trace ports supported up to 170 MHz, 4 or 8 bit width<br />

Halfrate Clock Mode supported<br />

1M Sample trace depth<br />

Timestamp resolution 1/ f CPU (i.e. 10ns at f CPU =100MHz)<br />

40bit time stamp range<br />

Support the full ETM functionality for providing the trigger events for the tracing unit<br />

Intelligent trace filter for optimal trace utilization<br />

Additional 8 external trace lines to observe peripherals and external signals<br />

LVDS interface to external connector pod supports pods for 38 pin ETM Mictor High-Speed<br />

Connector (proposed by ARM)<br />

Supported derivatives: LPC21xx, AT91RM9200<br />

38 Pin ARM7 and ARM9 Mictor<br />

High-Speed Connector Pod<br />

Recommended by ARM to<br />

support connection to ARM<br />

ETM<br />

Connector system based on<br />

Mictor 38 pin high-speed<br />

connector<br />

Prepared to use for systems<br />

up to 170MHz system clock<br />

Supports 2.5 Volt to 3.6 Volt<br />

I/O ring voltage<br />

80 pin cable to trace base<br />

board using LVDS interface<br />

to ensure high trace signal quality<br />

UDE Support of ETM Trace Functions<br />

The complete utilization of trace functionality by setup modes:<br />

<br />

<br />

<br />

<br />

1 standard mode to allow easy access to standard trace tasks<br />

Full connection of trace setup to symbolic reference of source code<br />

Visualization of internal and external trace events<br />

Browse capability between trace output and C-language sources<br />

UDE Support of ETB Trace Functions<br />

The Embedded Trace Buffer (ETB) extends the ETM unit of ARM derivatives by an embedded onchip<br />

circular trace buffer. This simplifies the adaptation of external trace units because the high<br />

speed trace signaling does not need to transfer to the external unit. The trace buffer is managed<br />

and read via the JTAG communication channel.<br />

<br />

Supported derivatives: LPC3000 derivatives<br />
