Selecting the Emulation Monitor Program

Selecting the Emulation Monitor Program
In order to select the type of monitor program used by the emulator, you must first
start the configuration interface and access the "Monitor Type" configuration
section (refer to the previous "Using the Configuration Interface" section).
This section shows you how to:

When you power up the emulator, or when you initialize it, the background monitor
is used by default. You can also configure the emulator to use a foreground
monitor. Before the background and foreground monitors are described, you
should understand the foreground and background emulator modes as well as the
function of the emulation monitor program.
The Background Emulator Mode
Background is the mode in which emulation processor execution does not appear
normally on the emulator probe. Background cycles may be driven to the target
system or hidden from the target system. When background cycles are driven, they
appear as reads. When background cycles are hidden, the emulator appears to the
target system to be in a suspended state. In background mode, the emulation
microprocessor executes out of background memory.
The Foreground Emulator Mode
Foreground is the mode in which all emulation processor cycles appear on the
emulation probe, and the emulator executes as if it were a real microprocessor. The
emulator is in foreground when it executes user programs. In foreground mode, the
emulation microprocessor typically executes out of target system or emulation
memory.
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 microprocessor.
