RTDX and High-Speed Debugging |

Until recently, developers were forced to stop their application with a breakpoint to exchange data "snapshots" with the host computer in a technique that’ called "stop-mode debugging". This intrusive approach can be misleading, because the isolated snapshot of a halted high-speed application cannot show the system’ real-world operation. To solve this problem, TI developed RTDX, or Real Time Data Exchange, which gives designers continuous, real-time visibility into their applications. RTDX was invented by TI in 1998 and was the first such capability in the DSP industry. RTDX enables real-time, asynchronous exchange of data between the target and the host, without stopping the target application. In essence, the RTDX data link provides a "data pipe" between DSP application and the host. The bidirectional capability allows developers to access data from the application for real-time visibility, or to simulate data input to the DSP, perhaps before real-time sensor hardware is available. This shortens development time by giving developers a realistic view of the way their systems operate.
