Internals

The internals subdirectory provides several common/utility facilities to both memory controllers and execution engines:

bounds.h and config.h

Define and check compile-time configuration of the monitor. See the User’s Guide for details on setting parameters.

Caution

To allow undefined preprocessors definitions to be detected as an error state, all flags must be defined in config.h and set to either EXHIBIT or INHIBIT (i.e., 1 or 0) and only checked for value - never existence!

debug.h

Provides debug preprocessor definitions, including printing macros and an UNUSED marker. See debug for more details.

errors.h and errors.c

Defines the r2u2_status enum used to signal error conditions throughout the monitor, as well as string conversion facilities for errors when in debug mode.

types.h

Definitions of parameterize types common to all components of the monitor, allowing for type punning.
