kurtosis block matches fixed-point library implementation again, now
with data-type propagation
modifications for 1-d bus/inport/outport instantiations
added new block generator functions & added docstrings for some old ones
minor changes to delay bram testbench
adding gitignore to filter simulink-generated trash
addition block generator functions (slice_off_top untested)
removed 'addsubmode'=TWO24 from DSP block instantiation because it was
causing simulation problems (that part of the model seems to access some
illegal memory, which crashes older versions of matlab and causes
out-of-memory errors in newer versions)
adding test bench for vector accumulator
DSP48E helper functions (control signals & concatenator for combined A:B
inputs)
changes to function call signature
adding MATLAB fixed-point library helper functions (used in block
generator functions)
changes corresponding to the changes to xblock bus functions
complex constant block. Used in fft_direct_init_xblock.m
squaring block
fft_direct block using helper function for pairing butterfly data inputs
blocks for abstracting to_workspace and from_workspace library blocks
block for abstracting from_workspace lib block
altered to reflect the changes to FFT to move the coefficient generators
outside of the butterfly block
added 'Position' parameter to make the generated block size smaller
test bench for phase rotation block in new fft structure
