HP E2466B Intel Pentium® Pro Preprocessor Interface

Product Summary

The HP E2466B preprocessor interface for the PentiumŪ Pro processor allows you to easily trace the operation of a PentiumŪ Pro processor system. The preprocessor and its transaction tracker software for the HP 16500B logic analysis system simplify the analysis of the PentiumŪ Pro multi processor bus. Bus transactions are summarized in the state listing display for rapid interpretation of bus operation. Bus timing diagrams displayed as waveforms are overlaid with status information for quickly indentifying bus conditions.

Product Features

• Capturing Transactions
  The HP E2466B keeps track of the Pentium® Pro processor, making it simple for you to analyze its operation. Because several transactions may be pending on the bus at one time, the preprocessor and transaction tracker keep track of the start and end of each bus phase. This information is used to save you time by presenting a state listing of bus activity grouped by complete transactions.
• Identifying Transactions
  The type is identified for you and presented in the analyzer's listing display. Each transaction displayed starts with the request type, such as memory read, I/O write or code read. Additional information includes error phase results, snoop results, response and data. Transaction duration measured in bus clocks is summarized at the end of each transaction listed.
• Selecting Transactions
  Focus your analysis of the activities on the bus by choosing to display those operations that give you the best view of the problem. A complete set of filters is included that allow you to selectively list transactions by agent and transaction type. For example, you can list only branch trace messages originating from agent 0.
• Displaying Bus Phase
  Each phase of a transaction is displayed in order of occurence. The HP E2466B clearly identifies and presents request, snoop, error, response and data phases.
• View Bus Timing
  Configuration software provided presets the HP 16500B logic analyzer's timing display into Pentium Pro processor bus-specific-signal groupings. Bus status information overlays each waveform group, enhancing your insight into the sequence of bus events. Bus timing measurement are made simply and directly using markers active in the logic analyzer timing display.

Clock qualification
Expanded mode:  Enables logic analyzer clocking while transactions are 
		outstanding on the Pentium Pro bus
Compacted mode:	Maximizes logic analyzer utilization by only enabling 
		clocking during transaction phases and transfer of reset 
		configuration information on the PentiumŪ Pro bus
