8 Complete implementation of adaptive arithmetic coding, suitable for Dirac 0.5.3 petebleackley 6493d 19h /
7 Added sources for exp-golomb encoding and decoding petebleackley 6559d 21h /
6 Added documentation for fixed-frequency encoder. petebleackley 6938d 01h /
5 Added documentation for fixed-frequency encoding.
Added component CONTEXT_MANAGER to handle conditional probability encoding.
Modified arithmetic coder, arithmetic decoder and testbench for conditional probability encoding.
FIFO now has a RAM based architecture, and it and INPUT_CONTROL are parameterised by width.
All flip-flops are now represented by clocked processes, so the components D_TYPE, ENABLEABLE_D_TYPE, STORE_BLOCK and COUNT_UNIT are no longer necessary.
Added input file "testseq" for testing conditional probability encoding.

4 Patch 1
Corrected errors in /src/common/ARITHMETIC_UNIT.vhd and /src/testbench/ArithmeticCoderTestbench.vhd
ARITHMETIC_UNIT.vhd
Corrected width of signal RESULT0 to (16 downto 0)
ArithmeticCoderTestbench.vhd
Removed extraneous inputs CONTEXT_ENABLE and CONTEXT_IN from component specification of ArithmeticCoder
(These belong to a future version)
Specified filename "raw_data" for file input TESTDATA
Added missing end if; in process OUTPUT
