Lauterbach Supports the 3G/DigRF Protocol for Cell Phones

Hofolding, July 2007 - LAUTERBACH, the manufacturer of microprocessor development tools and PowerIntegrator, the new Lauterbach logic analyzer, now supports the 3G/DigRF protocol. In mobile wireless applications, the baseband IC and the RF IC use this protocol to communicate with each other. PowerIntegrator typically operates together with the Trace32 ICD debugger, but can also operate as a stand-alone product.

ompanies for some time. Features such as multicore debugging (usually one or more ARM cores operate together with DSPs in a cell phone) and ETM tracing at rates up to 500 MHz make this debugger an indispensable tool. With PowerIntegrator and the 3G/DigRF probes, it is now possible to trace program flow and data movement on the 3G/DigRF interface with time correlation. The RX/TX channels are sampled at 2 GS/s; monitoring channels, such as SysClkEnable, are sampled at 250 MS/s. The high sensitivity of the probe and the low payload on the incoming signal guarantee faultless recording of the interface signal. Depending on the data transfer over these channels, the recording time varies from a minimum of 25.156 ms (approximately 8 MBits of 3G/DigRF at a rate of 312 MHz) to up to several hours. Data recording can be stopped by a break point, which can be triggered by a debugger or an ETM trace. The protocol analysis then displays each transferred frame protocol with detailed header and payload information. In addition to this chart representation, a graph of the run times of the I and Q data can also be displayed. For the purpose of offline analysis, recordings can be saved and exported as ASCII files. The user can also decide to further extend the functionality of the analysis software, for example, to interpret the payload content, since the c-code necessary for generating the DLL is also supplied. With recent software and a connection between a PowerIntegrator module and the 3G/DigRF probes, it is possible to extend the functionlity of any available Trace32 debugging tool.
