About This Writing Sample

VPQED™ Getting Started manual, Embedded Power Corp..

This Windows Help file is organized into four main sections, including General Information, Debugger Views, Operational Details, and a Command Reference. It is a complete reference, and provides programmers and engineers with specific information about how to implement standard debugging techniques using the QED™ in-circuit emulator and VisualProbe® debugger interface.

This Help file was originally the only documentation provided with the product. No printed versions were to be made available.

However, at our customers' requests, I later wrote a set of tutorials based on the contents of this file and on the many conversations about debugging techniques I had with engineers from Embedded Power (many thanks to Jerry Kilgore, Eric Overton, Chuck Watson, and Ford Frost), 3DO - those gaming fanatics, Boundless Technology, and many others.

About VisualProbe Q.E.D. 186

VisualProbe Q.E.D. 186 is an in-circuit emulator (Q.E.D.) controlled by Windows based debugger interface (VisualProbe).

These products are used with several different AMD and Intel 186 microprocessors by embedded developers who need to control the debugging process with a high degree of bus-level visualization and control.

The Q.E.D. in-circuit emulator replaces the microprocessor with a microprocessor whose functions are placed directly under the control of the VisualProbe debugger software. All events that take place in the processor can be monitored by the debugger software. The programmer can define any hardware event or value to trigger a specific debugger response. The debugger interface provides what is essentially a microscopic real time, recorded, or freeze-framed view of hardware states, program code, and their interactions.
