Parameters specific to the block are:
•
Force Arithmetic Type : When checked, the Output Arithmetic Type
parameter can be set and the output type will be forced to the arithmetic type
chosen according to the setting of the Output Arithmetic Type parameter. When
unchecked, the arithmetic type of the output will be unchanged from the
arithmetic type of the input.
•
Force Binary Point Position : When checked, the Output Binary Point
parameter can be set and the binary point position of the output will be forced to
the position supplied in the Output Binary Point parameter. When unchecked, the
arithmetic type of the output will be unchanged from the arithmetic type of the
input.
•
Output Arithmetic Type : The arithemetic type (unsigned or signed, 2’s
complement) to which the output is to be forced.
•
Output Binary Point : The position to which the output’s binary point is to be
forced. The supplied value must be an integer between zero and the number of
bits in the input (inclusive).
This block does not use any hardware resources. The block does not use a Xilinx
LogiCORE.
Serial to Parallel
The Serial to Parallel block takes a series of inputs of any size and
creates a single output of a specified multiple of that size. The input
series can be ordered either with the most significant word first or the
least significant word first.
