Foreground or
When you power up the emulator, or when you initialize it, the
background monitor is used by default. You can also configure the
Background
emulator to use a foreground monitor. Before the background and
Emulation Monitor
foreground monitors are described, you should understand the function
of the emulation monitor program.
The Function of the Monitor Program
The monitor program is the interface between the emulation system
controller and the target system. The emulation system controller uses
its own microprocessor to accept and execute emulation system, and
analysis commands. The monitor program is executed by the
emulation processor.
The monitor program makes possible emulation commands which
access target system resources. (The only way to access target system
resource is through the emulation processor.) For example, when you
enter a command to modify target system memory, it is the execution
of monitor program instructions that cause the new values to be written
to target system memory.
The Background Monitor
On emulator power-up, or after initialization, the emulator uses the
background monitor program. The background monitor does not
occupy processor address space.
The Foreground Monitor
You can configure the emulator to use a foreground monitor program.
When a foreground monitor is selected it executes in the foreground
emulator mode. The foreground monitor occupies processor memory
space and executes as if it were part of your program.
Register Display and
You can display or modify the 7750/51 Series internal register
contents. This includes the ability to modify the program counter (PC)
Modification
and the program bank register (PG) values so you can control where the
emulator starts a program run.
