Parameters specific to this block are:
•
Depth : specifies the number of words stored; must be a positive integer.
•
Initial Value Vector : specifies the initial value. When the vector is longer
than the ROM depth, the vector’s trailing elements are discarded. When the ROM
is deeper than the vector length, the ROM’s trailing words are set to zero.
•
Word Type : specifies the data to be Signed or Unsigned.
•
Number of Bits per Word : specifies the number of bits in a memory word.
•
Binary Point for Words : specifies the location of the binary point in the
memory word.
•
Use Distributed Memory (instead of Block RAM) : when checked, the
block is implemented with distributed RAM. Otherwise it is implemented with
Block RAM.
