Heinz-Bernd Eggenstein authoredexperimental: -added alternative method for twiddle factor calc, using a smaller LUT (256 * float2 ) via Taylor series to 3rd order, seems to be almost as accurate as method with 2 bigger LUTs, but faster. -improved method w/ 2 bigger LUTs to use LUTs of float2 -improved method using slow sin/cos functions (now uses sincos combined function), still slow - preparaed plan struct to have method switchable at plan creation time. TODO: load smaller LUT for Taylor series approx into shared mem.Heinz-Bernd Eggenstein authoredexperimental: -added alternative method for twiddle factor calc, using a smaller LUT (256 * float2 ) via Taylor series to 3rd order, seems to be almost as accurate as method with 2 bigger LUTs, but faster. -improved method w/ 2 bigger LUTs to use LUTs of float2 -improved method using slow sin/cos functions (now uses sincos combined function), still slow - preparaed plan struct to have method switchable at plan creation time.

modules 1.12 KiB
# Three different line formats are valid:
# key -a aliases...
# key [options] directory
# key [options] directory files...
#
# Where "options" are composed of:
# -i prog Run "prog" on "cvs commit" from top-level of module.
# -o prog Run "prog" on "cvs checkout" of module.
# -e prog Run "prog" on "cvs export" of module.
# -t prog Run "prog" on "cvs rtag" of module.
# -u prog Run "prog" on "cvs update" of module.
# -d dir Place module in directory "dir" instead of module name.
# -l Top-level directory only -- do not recurse.
#
# NOTE: If you change any of the "Run" options above, you'll have to
# release and re-checkout any working directories of these modules.
#
# And "directory" is a path to a directory relative to $CVSROOT.
#
# The "-a" option specifies an alias. An alias is interpreted as if
# everything on the right of the "-a" had been typed on the command line.
#
# You can encode a module within a module by using the special '&'
# character to interpose another module into the current module. This
# can be useful for creating a module that consists of many directories
# spread out over the entire source repository.
