The Evaluation Process

required. VisualDSP++ provides core cycle-accurate simulators, allowing inspection of every nuance of activity within the processor, including visu- alization of the processor’s pipeline and cache.

As many of the most performance-demanding applications process a signal of some sort, comprehensive memory plotting is a corner stone of Visu- alDSP++ debugger support. VisualDSP++ provides multiple views, from basic (line plots) to sophisticated (eye diagrams and waterfalls) to pinpoint anomalous data sequences in your application. Image viewing in a number of data formats is also available.

VDK users get unparalleled visibility into the internals of the kernel. Sta- tus on a per-thread basis is available, as is a comprehensive pictorial history of kernel events and CPU loading. Thread changes, posted and pended semaphores, and other kernel events are captured in this display.

Inspection, or even application stimulation, from the debugger at runtime is possible through the use of the processor’s background telemetry chan- nels (BTCs). BTC allows for an arbitrary number of communication channels to be established between the host debugger and the application. Channels may go in either direction, so BTC can be used to read and write data as the processor runs. Scalar values or entire arrays may be ser- viced by a channel. Arrays read from the target can even be plotted in real time.

Multiprocessor users get the same compelling set of debugging features across all processors, unified into a single debugging interface. Individual windows can be made to “float” their focus to whichever processor cur- rently is the debugger’s focus, or they can be “pinned” to a specific processor so their contents do not follow the debugger’s focus. To further aid MP debug, synchronous run, step, halt, and reset are also provided.

The patented statistical profiler from Analog Devices offers unprecedented and unique visibility into a running application. Operating completely non-intrusively to the application, the application is polled thousands of times per second and a statistical view of where an application is spending
