# CpuModel class

# The CpuModel class encapsulates everything the ISA parser needs to
# know about a particular CPU model.
class CpuModel:
# Dict of available CPU model objects. Accessible as CpuModel.dict.
dict = {}
# Constructor. Automatically adds models to CpuModel.dict.
def __init__(self, name, filename, includes, strings):
self.name = name
self.filename = filename # filename for output exec code

# substitute into templates etc.

# Define CPU models.

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