Overview of RMHost

1.1About RMHost

RMHost is the host component of RealMonitor. It allows you to perform nonstop debugging on a RealMonitor-enabled application in a real-time environment. That is, when using RMHost, you can perform certain debugging operations on a foreground application while the processor continues to run (and service interrupts) in the background.

The functionality of RMHost is contained in the RMHost controller, RealMonitor.dll, which provides a standard Remote Debug Interface (RDI) to the debugger. The debugger communicates with the debug target using the RMHost controller, and communication between RMHost and RMTarget is governed by the RealMonitor protocol. These component parts of RealMonitor, and the connection between them, are shown in Figure 1-1.
