#	NOTE ON DEBUGGING
#
#	The IDCT algorithm operates in two passes (horizontal and vertical)
#	In each pass, 8 1-D IDCT are performed
#	To debug the IDCT algorithm, add -DONEPASS. This allows
#	the intermediate results to be examined.
#
#	To compare with  reference results, use
#		fidct -sep -onepass < <input file>
#
#	A good input file is data/test2d.2. This contains the 8 basis
#	vectors 
#
#	This release has greatly expanded example source code. Look
#	at the comments in the individual files

#
#	The standard makefile entry checks that running the IDCT
#	against the DCT produces the same results 

check:
	-mkdir ref tmp
	make clean
	make fidct
	@for endian in el eb ; \
		do \
		echo Endian= $${endian}, ... Compiling -- ; \
		make ENDIAN=$${endian} compile ; \
		for a in input.linear input.rand test2d.2 blksample.1 blksample.2 blksample.3 blksample.4 blksample.5 blksample.6 input.2 ; \
			do \
			echo -n ... Input $$a "..."  ; \
			$(TCS)/bin/tmsim idct.out <data/$$a >tmp/$$a ; \
			fidct <data/$$a >ref/$$a; \
			echo `cmp -l ref/$$a tmp/$$a | wc -l` Differences;\
			done ; \

#	This is a 1-D fixed point implementation

#
#	This is a reference DCT implementation. It is provided

fidct: fidct.c
	$(HOSTCC) fidct.c  -o fidct -lm

#
#	This is a 1-D floating point version of the DCT. This is used
#	in initial debugging

one_d.float: one_d.float.c
	$(HOSTCC) -I../tc one_d.float.c -o one_d.float -lm

#
#	This program accepts data files with the old shuffle order and
#	produces a standard DCT order
#

shuffle.out: shuffle.c
	$(HOSTCC) shuffle.c -o shuffle.out 

#
#	The coefficient generator program is provided with
#	the sources. Coefficients are packed as fixed point,
#	the msb is the sign, with 14 bits for the fraction

	$(HOSTCC) make_coeffs.c -o make_coeffs -lm -lsunmath

#	This is the core entry of the 2D DCT. The DCT is an unrolled
#	completely algorithm using fixed point arithmetic. For more
#	information, refer to Sang Ju Parks article and the article
#	in the cookbook, also the references
