The AX386 dedicated emulator offers powerful Real-Time debugging for Intel
386(TM)EX/SX microprocessors at a new low cost. The AX386 uses the same
technology as the popular teletest32 emulator for the Intel386(TM)DX/EX/SX.
The AX386 offers non-intrusive, real-time emulation of the target under
test. No cycle-stealing, wait-state introduction or stopping of the CPU
occurs. The Real to Protected mode transition (mixed mode) can be
debugged with HiTOP. HiTOP allows the display and changing of the Hidden
Register Cache and of the Test Registers. HiTOP displays long addresses,
opcodes and mnemonics with the column configurable Instruction Window.
Breakpoints stop the emulation before executing the instruction where the
breakpoint is set. They can be set in ROM as well as writable memory
locations.
The Special Function Registers of the processor are displayed in plain
English rather than bit patterns or hexadecimal codes. The need to consult
data books or decode obscure codes is eliminated. These registers are
easily changed within HiTOP with mouse clicks, and the user is prompted with
the possible choices.
Complicated data structures are easily followed by merely clicking on the
structure's name in the Examine Window. Structures within structures may
be displayed by continuing this process. The debugging process is greatly
simplified using this process.
Sophisticated filtering mechanisms for the trace function allow a smaller
trace memory to be used freeing up resources for other important emulator
features. Processor cycles are stored in terms of the High Level Language
source lines. A minimum of trace memory (only two frames per line) are
used no matter how complicated the line is. Trace recording using the Raw
Cycles Method is still available. Benefits are the ease of finding
problems areas in your source code and the expanded trace regions and trace
filtering features that are made possible with this Hitex system.
