Hash-Partition primitive.

Parameters:

HASH_MODE	0 for radix and 1 for Jenkin’s Lookup3 hash.
KEYW	width of key, in bit.
PW	width of max payload, in bit.
EW	element data width of input table, in bit.
HASHWH	number of hash bits used for PU selection.
HASHWL	number of hash bits used for partition selection.
ARW	width of address for URAM
CH_NM	number of input channels, 1,2,4.
COL_NM	number of input columns, 1~8.
mk_on	input of double key flag, 0 for off, 1 for on.
depth	input of depth of each hash bucket in URAM.
bit_num_strm	input of partition number, log2(number of partition).
k0_strm_arry	input of key columns of both tables.
p0_strm_arry	input of payload columns of both tables.
e0_strm_arry	input of end signal of both tables.
o_bkpu_num_strm	output of index for bucket and PU
o_nm_strm	output of row number each time
o_kpld_strm	output of key+payload
