BufferUp
- Luis Casarrubias
Overview
Buffers the input into larger block sizes. Non-overlapping
Discussion
This module is the interface between small block processing and large block processing. The module buffers up small blocks of data into larger non-overlapping blocks. The larger blocks are executed in a lower priority thread compared to the smaller blocks. The module works on any 32-bit data type including integer, fract32, and floating-point.
The module is similar to the rebuffer_module.m. The rebuffer_module buffers up into OVERLAPPING blocks while this module buffers up into NONOVERLAPPING blocks.
The argument OUTBLOCKSIZE determines the blockSize of the output pin. If OUTBLOCKSIZE is positive, then the output blockSize equals OUTBLOCKSIZE. If OUTBLOCKSIZE is negative, then the output blockSize equals the input blockSize times (-OUTBLOCKSIZE).
Note, not all targets support this. Check the target documentation to see how many levels of audio processing are supported.

MATLAB Usage
File Name: buffer_up_subsystem.m
SYS=buffer_up_subsystem(NAME, OUTBLOCKSIZE)
Create a module which buffers up data into a larger block size. The buffering
is non-overlapping and the downstream processing occurs at a decimated block
rate. Arguments:
NAME - name of the module.
OUTBLOCKSIZE - specifies the blockSize of the output pin. If OUTBLOCKSIZE
is positive, then the blockSize of the output pin equals OUTBLOCKSIZE.
If OUTBLOCKSIZE is negative, then the blockSize of the output pin equals
(-OUTBLOCKSIZE) times the blockSize of the input pin.Â
