Glossary
simulated I/O The debugger feature that lets user programs read input from,
and write output to, the same keyboard and display (respectively) that are used
to control the debugger. Simulated I/O also lets user programs use the UNIX
file system and run UNIX commands.
simulated program interrupt User program interrupts that are simulated by
the debugger. Simulated interrupts can be one-time interrupts or periodic
interrupts.
simulator A software tool that simulates a microprocessor system for the
purpose of debugging user programs.
Software Probe The HP E3490A software probe is a low-cost alternative to
an emulator. It uses the processor's Background Debug Mode to control
execution and to access registers and memory. Because it does not include an
analyzer, the HP E3490A software probe does not support read/write
breakpoints or trace analysis.
SPA The HP Software Performance Analyzer.
standard interface The traditional debugger interface designed for use with
several types of terminals, terminal emulators, and bitmapped displays. When
using the standard interface, commands are entered from the keyboard.
startup file A file that contains information regarding debugger options and
screen configurations.
state file A file that contains the CPU state (including register values) and a
memory image. This file is saved within a debugger session and can be loaded
at a later time to return to a particular state of execution.
status line A line which displays debugger information such as the CPU
type, the current module name, and the current debugger operation.
sticky slider A scrollbar slider which is designed for local navigation in a
large file. Moving the slider moves the contents of the active window just a
few pages at a time.
storage qualifier A bus cycle state description that causes only particular
states to be stored in the analyzer trace.
