# freqdat.py
|
|
# You can use this to generate an alternative SAAFreq.dat
|
|
#
|
|
# By default, the SAA-1099 generator will compute a frequency table at runtime
|
|
# but you can set the SAA_FIXED_CLOCKRATE define flag and supply your own (fixed,
|
|
# precompiled) frequency table named SAAFreq.dat
|
|
#
|
|
# This is not super-useful for general-purpose computing devices (e.g PCs), but is
|
|
# useful for embedded or low-capability devices, or for hardware-based implementations
|
|
#
|
|
# To use this simply run the file and pipe the output into src/SAAFreq.dat
