The Serial to Parallel block takes a series of inputs of any size and creates a single output of a specified multiple of that size. The input series can be ordered either with the most significant word first or the least significant word first.

The following waveform illustrates the block's behavior:

Figure 1. Serial to Parallel Behavior

This example illustrates the case where the input width is 1, output width is 4, word size is 1 bit, and the block is configured for most significant word first.

Block Interface

The Serial to Parallel block has one input and one output port. The input port can be any size. The output port size is indicated on the Block Parameters dialog box.

Block Parameters

The block parameters dialog box can be invoked by double-clicking the icon in your Simulink® model.

Basic tab
Parameters specific to the Basic tab are as follows.
Input order
Least or most significant word first.
Arithmetic type
Signed or unsigned output.
Number of bits
Output width which must be a multiple of the number of input bits.
Binary point
Output binary point location

Other parameters used by this block are explained in the topic Common Options in Block Parameter Dialog Boxes.

An error is reported when the number of output bits cannot be divided evenly by the number of input bits. The minimum latency for this block is zero.
