		float *	window,
		int *	dither_state,
		float *	samples,
		int	incr
	)			[static]

instructions are scheduled to minimize pipeline stall. use of round_sample function from the original code is changed with appropriate assembly instructions.

	)			[static]

all loops are unrolled totally, and instructions are scheduled to minimize pipeline stall. instructions of the first two loops are reorganized, in order to eliminate unnecessary readings and writings into array. values defined in macros and tables are eliminated - they are directly loaded in appropriate variables
