# CpuModel class
#
# The CpuModel class encapsulates everything the ISA parser needs to
# know about a particular CPU model.

    # Dict of available CPU model objects.  Accessible as CpuModel.dict.
    dict = {}

    # Constructor.  Automatically adds models to CpuModel.dict.

# Parameters are:
#   - name of model
#   - filename for generated ISA execution file
#   - includes needed for generated ISA execution file
#   - substitution strings for ISA description templates
