The Vector Multiplexer block supports the Multiplexing feature for input of vector types.

Description

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

The Vector Mux block implements a multiplexer. The block has one select input (type unsigned) and a user-configurable number of data bus inputs, ranging from 2 to 1024.

Block Parameters

Open the Block Parameters dialog box by double-clicking the icon in your Simulink® model.

Basic tab
Number of inputs
Specify a number between 2 and 32.
Optional Ports

Other parameters used by this block are explained in the topic [Block Parameters] ダイアログ ボックスの共通オプション.

Output tab
Precision

This parameter allows you to specify the output precision for fixed-point arithmetic. Floating-point arithmetic output will always be Full precision.

Full
The block uses sufficient precision to represent the result without error.
User Defined
If you do not need full precision, this option allows you to specify a reduced number of total bits and/or fractional bits.
Fixed-point Output Type
Arithmetic type
Signed (2’s comp)
The output is a Signed (2’s complement) number.
Unsigned
The output is an Unsigned number.
Fixed-Point Precision
Number of bits
Specifies the bit location of the binary point of the output number where bit zero is the least significant bit.
Binary point
Position of the binary point. in the fixed-point output.
Quantization
