Q.E.D. Install Manual - Chapters 1 & 3

In the original manual, with four chapters, I describe how to set up the Q.E.D. hardware with specific instructions for installing several different COMM cards, and for using the unit with several different host machines, operating systems, and microprocessors.

The number of install variations that are possible requires several sections of reference material regarding jumper positions on the probe unit (the unit that contains the Q.E.D.'s microprocessor). Chapter 3 deals with specific instructions for each microprocessor manufacturer, ONCE mode in AMD/Intel microprocessors, read/write specifications for control block registers, clock signals, and provides many other references to considerations that must be taken for proper operation with various microprocessors.

A separate section of the manual deals with setting up the QED Jtag Debugger for use with Pentium™ and other microprocessors using the JTAG instruction set. This includes considerations for header adapters for target systems with no built-in headers. I have included some drawings of several JTAG adapters in the Illustration section of the portfolio.

The final chapter of the manual deals with porting Logic State Input signals from other sources on the target system into the Q.E.D. ICE unit that can aid in analysis.

About the Product

Q.E.D.™ is an in-circuit emulator used by embedded systems developers to replace the microprocessor in the 186 386 target system under development. Yes, they are still in use!

An in-circuit emulator provides complete control over microprocessor functions, enabling developers to identify problems in their embedded projects quickly. The emulator functions under the control of debugger software - in this case Beacon Technology's VisualProbe®, running under Microsoft Windows®.

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.

This unit is no longer being manufactured. However, existing units can be serviced completely at Spiral Alliance of Round Rock, TX.
