CODER.H This is the header file needed to use CODER.C.
CODER.C This file contains the routines needed to implement
an arithemtic coder.
BITIO.H This is the header file needed to use BITIO.C.
BITIO.C This is the module used to do bit-oriented I/O.
COMP-1.C This is the main module for a fixed-context
compression program. It is used to drive MODEL-1
and MODEL-1A. It doesn't know about escape codes.
EXPAND-1.C This is the main module for a fixed-context
decompression program. It is used with MODEL-1
and MODEL-1A. Doesn't know about escape codes,
order (-1) models, or any of that stuff.
MODEL.H This is the header file that is used when working
with any of the modeling modules.
MODEL-1.C This is the modeling model for a very siple order-0
fixed context model. To be used with COMP-1 or
EXPAND-1.
COMP-2.C This is the main module for a highest-context
compression program. It handles escape codes, and
does compression ratio checking as well. It is
used with MODEL-2 and MODEL-2A.
EXPAND-2.C This is the main module for a highest-context
decompression program. It understands all of the
fancy stuff used in MODEL-2 and MODEL-2A.
MODEL-2.C This is the highly optimized source for a
variable order compression program. It is
used with COMP-2 or EXPAND-2.
MODEL-1A.C This is an order-1 fixed context modeling unit, that
can be combined with COMP-1 and EXPAND-1. Used
to test compression for higher order models that
don't use escape codes.
MODEL-2A.C This is the source for an order-1 highest-order
modeling program. It understands escape codes,
but has a simple data structure that takes up a
lot of room. So it is fast, but takes up lots
of RAM. Can't be expanded beyond order-1 in a
PC due to memory limitations.
