rebuffer_delay
Number of samples of delay introduced by buffering and unbuffering operations
Syntax
d = rebuffer_delay(f,n,v)
d = rebuffer_delay(f,n,v,'mode')
Description
d = rebuffer_delay(f,n,v)
returns the delay,
in samples, introduced by the Buffer or Unbuffer block in multitasking operations.
d = rebuffer_delay(f,n,v,'mode')
returns
the delay, in samples, introduced by the Buffer or Unbuffer block
in the specified tasking mode.
Input Arguments
|
Frame size of the input to the Buffer or Unbuffer block. |
|
Size of the output buffer. Specify one of the following:
|
|
Amount of buffer overlap. Specify one of the following:
|
|
The tasking mode of the model. Specify one of the following options:
Default: |
Examples
Compute the delay introduced by a Buffer block in a multitasking model:
Open a model containing a Buffer block. For this example, open the
ex_buffer_tut4
model by typing ex_buffer_tut4 at the MATLAB® command line.Double-click the Buffer block to open the block mask. Verify that you have the following settings:
Output buffer size = 3
Buffer overlap = 1
Initial conditions = 0
Based on these settings, two of the required inputs to the
rebuffer_delay
function are as follows:n = 3
v = 1
To determine the frame size of the input signal to the Buffer block, open the Signal From Workspace block mask. Verify that you have the following settings:
Signal =
sp_examples_src
Sample time =
1
Samples per frame =
4
Because Samples per frame =
4
, you know thef
input to therebuffer_delay
function is4
.After you verify the values of all the inputs to the
rebuffer_delay
function, determine the delay that the Buffer block introduces in this multitasking model. To do so, type the following at the MATLAB command line:d = rebuffer_delay(4,3,1) d = 8
Compute the delay introduced by an Unbuffer block in a multitasking model:
Open a model containing an Unbuffer block. For this example, open the
ex_unbuffer_ref1
model by typing ex_unbuffer_ref1 at the MATLAB command line.To determine the frame size of the input to the Buffer block, open the Signal From Workspace block mask by double-clicking the block in your model. Verify that you have the following settings:
Signal =
sp_examples_src
Sample time =
1
Samples per frame =
3
Because Samples per frame =
3
, you know thef
input to therebuffer_delay
function is3
.Use the
rebuffer_delay
function to determine the amount of delay that the Unbuffer block introduces in this multitasking model. To compute the delay introduced by the Unbuffer block, usef = 3
,n = 1
andv = 0
.d = rebuffer_delay(3,1,0) d = 3
