HP E2412A Intel i860XP Preprocessor Interface

Product Summary

The HP E2412A provides an easy way to connect your Intel i860XP target system to an HP logic analyzer. The preprocessor provides a complete electrical and mechanical interface between your target system and an HP logic analyzer. Included with the E2412A is software which automatically configures the analyzer labeling address, data, and status lines. The inverse assembler decodes bus activity and displays i860XP mnemonics in state listings.

Product Features

• Use state analysis with inverse assembly to track your system's software flow in your microprocessor's mnemonics.

• Locate hardware design problems or bus contentions in your i860XP system using the logic analyzer's timing analysis.

• Identify software defects and monitor the value of variables stored in memory using your instrument's state analysis with inverse assembly.

• Capture all bus cycles with the logic analyzer while operating with the internal cache memory disabled for correct inverse assembly.
