The Scalar2Vector block converts scalar type input to vector type output.


The Xilinx® Scalar2Vector block slices the binary value of the input scalar based on the Width parameter to produce a vector output. For example, if the input is 3720 ( binary value 111 010 001 000 ) of type Ufix_12_0, SSR is 4, and the Width parameter value is 3, then this block slices the input binary value into 4 groups, each of 3 bits, so that it produces the output [0 1 2 7].

Data Type Support

The input must be a Boolean or unsigned fixed-point signal. The output type is normally unsigned with binary point at zero, but can be Boolean when the Width parameter is 1.

Block Parameters

Width: This parameter defines the number of bits for each element of output vector. This parameter is decided by:

Width = Input data width (bits)/SSR

This formula must be satisfied when setting up the block parameters.

Super Sample Rate (SSR): This configurable GUI parameter is primarily used to control the processing of multiple data samples on every sample period. This block enables 1-D vector support for the primary block operation.
