Serial-In Parallel-Out Shift Register block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simscape / Electrical / Control / General Control

Description

The Serial-In Parallel-Out Shift Register block implements a serial-in parallel-out shift register in discrete time. You can use a shift register to convert between serial and parallel interfaces or to implement a circuit delay or hardware stack.

This block outputs a vector of last N samples of the input signal. If the input signal is a vector, the block outputs the last N samples of each input signal.

Ports

Input

u — Serial input

scalar | vector

Serial input signal.

Data Types: single | double

Output

y — Parallel output

vector

Parallel output signal.

Data Types: single | double

Parameters

Number of samples — Number of input samples

4 (default) | positive integer

Number of register stages or samples.

Initial condition — Initial value of the input sample

0 (default) | real number

Initial value of the N-1 samples preceding simulation start time. The value must be a scalar or a vector of the same size as the input signal.

Sample time (-1 for inherited) — Block sample time

-1 (default) | 0 | positive scalar

Time between consecutive block executions. During execution, the block produces outputs and, if appropriate, updates its internal state. For more information, see What Is Sample Time? and Specify Sample Time.

For inherited discrete-time, specify -1. For discrete-time, specify a positive integer. For continuous-time, specify 0.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"ee_sl_lib/General Control/Serial-In Parallel-Out Shift Register"

Example: add_block("ee_sl_lib/General Control/Serial-In Parallel-Out Shift Register","myModel/myBlock",MakeNameUnique="on")
