HP E2457A Preprocessor for Pentium® Processor & Pentium Processor with MMX™ Technology

Product Summary

The HP E2457A preprocessor interface for the Pentium processor and Pentium Processor with MMX Technology allows you to easily connect an HP logic analyzer to your target system.

The preprocessor has three modes of operation. First, in state-per-transfer mode, the logic analyzer is clocked upon completing data transfer cycles. In this mode, the preprocessor keeps track of the address pipeline and aligns data with its parent address. The second mode of operation is state-per-clock. Data is captured on every system clock, so you see all processor activity, including wait and idle states. This mode of operation is useful in finding memory locations that do not respond with data and checking memory control systems. The final mode of operation is timing analysis. All signals are buffered, but otherwise pass straight through to the logic analyzer.

Software is included that automatically configures the logic analyzer, labeling address, data, and status lines. Additionally, an inverse assembler displays execution traces in Pentium processor and Pentium Processor with MMX Technology mnemonics.

Product Features

• Captures all bus cycles, including prefetches
• Marks all unexecuted prefetches
• Supports disassembly of floating point instructions
• Calculates and displays burst mode addresses in the state trace listing
• Supports timing analysis where all signals are buffered

Product Specifications

Microprocessor Compatibility

Logic Analyzers Supported

Pods Required

Eight, 16-channel pods are required for inverse assembly. Two additional pods provide monitoring of other status signals.

Adapters

All pods are terminated on the probe so you don't need to order additional termination adapters.
