REAL-TIME DATA EXCHANGE

In the past, DSP application designers have gathered data by stopping a target application at designated breakpoints to read registers and other data storage locations. This practice is not only cumbersome, it can provide misleading data because it yields only a snapshot obtained by suddenly stopping a high-speed application - a readout that may not present an accurate view of the system's continuous operation.

This paper presents the Texas Instruments (TI(TM)) digital signal processing (DSP) analysis technology, Real-Time Data Exchange (RTDX(TM)). RTDX offers developers continuous bi-directional data exchange in real time with minimal perturbation on the application. Because RTDX uses TI's universal JTAG data path and TI's debugger, it can be supported on every TI processor without assuming any particular I/O peripherals and can also use other data interfaces instead of or in addition to JTAG.

RTDX displays data using your favorite OLE-enabled visualization package, is easy to program on both target and host, and is provided at no additional cost, bringing substantial value to TI's DSP solutions.
