What the parameters "kShiftData" in matmul_tb.cc mean?

[sxbkdby8]

I can't find any other references about this variable.
Thank you for your help!

Hi. Yes. We are still working on it and will improve the documentation.

The kShiftData can be computed as the log2(kPackets), where kPackets is the number of data that can fit in the bus (kBus).

I saw it is undefined, so, you can replace the

  int size_a = a_rows * (b_cols >> kShiftData);
  int size_b = c_cols * (b_cols >> kShiftData);
  int size_c = a_rows * (c_cols >> kShiftData);

by

  int size_a = a_rows / kPackets;
  int size_b = c_cols / kPackets;
  int size_c = a_rows / kPackets;

Cheers,
Leon
