Int32 vs Int64 for analog waveforms #11

Closed paulmthompson closed 8 years ago

paulmthompson commented 8 years ago

For SpikeSorting.jl and Intan.jl, I have used Int64s for all of the raw data that is streamed from the FPGA for consistency. The board only uses Int32s, so I wonder if making this change could lead to some performance benefits, particularly with writing the data.

Each sample is only two bytes, signed or unsigned. Plotting or saving two bytes per sample should be sufficient (int16 or uint16), and saves space.

Word size converted to Int16 with https://github.com/paulmthompson/Intan.jl/commit/621e3f9ce46e05423b2e979137b2af8e0557a2b3
