Buffers, Switches, and Counters

Change sample rate or frame rate of signals, count events, detect edges, perform actions when events occur

Objects

`dsp.AsyncBuffer`	FIFO buffer
`dsp.DelayLine`	Rebuffer sequence of inputs with one-sample shift
`dsp.Counter`	Count up or down through specified range of numbers

rebuffer_delay Number of samples of delay introduced by buffering and unbuffering operations

Buffer	Buffer input sequence to smaller or larger frame size
Delay Line	Rebuffer sequence of inputs
Queue	Store inputs in FIFO register
Stack	Store inputs into LIFO register
Unbuffer	Unbuffer input frame into sequence of scalar outputs

Counter	Count up or down through specified range of numbers
Edge Detector	Detect transition from zero to nonzero value
Event-Count Comparator	Detect threshold crossing of accumulated nonzero inputs
Multiphase Clock	Generate multiple binary clock signals
N-Sample Enable	Output ones or zeros for specified number of sample times
N-Sample Switch	Switch between two inputs after specified number of sample periods

Learn how operations such as direct rate conversion and frame rebuffering impact the sample and frame rates if your signal.

Introduction to real-world sample- and frame-based signals, and how to model those signals in MATLAB^® and Simulink^®.

Convert signals of frame size 1 into signals of frame size greater than 1, and vice versa.

Learn how to determine the sample and frame rates of signals in your model.

Configure the Simulink environment to minimize delay and increase simulation performance.

Resolve the dimension mismatch error when you read data from an async buffer inside the MATLAB function block.

Initialize the async buffer by calling either setup or write before the first call to read.

Push and pop elements from a queue using a Queue block with a system of selection switches.
