HP E2465A Preprocessor Interface for the PowerPC 604 Microprocessor

Product Summary

The HP E2465A preprocessor interface allows easy connection of an HP logic analyzer to your PowerPC 604 target system so you can trace processor activity in real-time, nonintrusively. Software provided with the preprocessor automatically configures the logic analyzer for use with the preprocessor. The software also includes an inverse assembler, which gives you PowerPC 604 mnemonics in the trace listing for easy correlation between captured data and target code.

Product Features

• Stack-per-ack: the logic analyzer uses trigger sequencer store qualifications to capture only address and data acknowledge cycles. The only states recorded are those in which one or more of the strobes (AACK,TS, ARTRY, TA, DRTY) is asserted. This default mode is set by the configuration files and provides the greatest information density to the logic analyzers‚ acquisition memory.

• State-per-clock: the logic analyzer captures every clock cycle, including idle and wait states, between and during tenures. Address, data, and status are captured on each CPU clock. This mode is useful for hardware validation and debugging system crashes.

• Timing analysis: The logic analyzer samples the microprocessor pins asynchronously, with 4 ns resolution typical. This mode is used when accurate timing measurements are needed.

• Address and data alignment
• Synchronization of branch addresses
• Display of general purpose, floating point, condition, and special purpose registers
• Full decode of PowerPC 604 instruction set
• Support of extended mnemonics, including conditonal traps, add-immediate, subtract-from, and rotate-left.

Product Specifications

The HP E2465A preprocessor interface has a Pin Grid Array (PGA) footprint. The connector on the preprocessor interface plugs directly into the PGA socket on the target system. To connect the preprocessor, remove the PowerPC 604 chip from the target system and plug it into the socket on the preprocessor interface. Then, plug the preprocessor interface into the target's socket. Note: the PowerPC is not keyed, so caution must be used when positioning the chip in the target.

For easy extraction, it is strongly recommended that a pin protector be placed on the PowerPC 604 chip before inserting it into the target socket.

Microprocessor Modes Supported

The preprocessor supports normal, Fast-L2, and direct store modes.

Accessories Required

None

Termination Adapters

All analysis probes are terminated on the preprocessor. No additional termination adapters are required.

These configurations show the number of analysis cards needed in the mainframe. Each card has analysis pods and probes, which connect to high-density termination adapters on the preprocessor. Eight 16-channel analyzer pods are the minimum required to perform inverse assembly and monitor all signals from the processor.

Run Control

The HP E2465A has a JTAG connector on board for easy connection to the PowerPC's JTAG port. This connector also can be used to connect a run control tool, such as a processor probe.

Electrical Characteristics

Power Requirements:

Up to 75% noncondensing. Avoid sudden, extreme temperature changes which could cause condensation on the circuit board.
