  • Wireless HDL Toolbox / Utilities

  • Sample Control Bus Creator block

Description

The Sample Control Bus Creator block creates a samplecontrol bus for modeling streaming control signals in communication systems for hardware. See Sample Control Bus.

The block is an implementation of the Simulink® Bus Creator block. See Bus Creator for more information.

Ports

Input

expand all

Start of frame, specified as a Boolean scalar. This signal is 1 (true) for one time step, corresponding to the first valid sample of the frame.

Data Types: Boolean

End of frame, specified as a Boolean scalar. This signal is 1 (true) for one time step, corresponding to the last valid sample of the frame.

Data Types: Boolean

Validity of samples, specified as a Boolean scalar. This signal is 1 (true) on time steps that correspond to valid samples.

Data Types: Boolean

Output

expand all

Control signals accompanying the sample stream, returned as a samplecontrol bus. The bus includes the start, end, and valid control signals, which indicate the boundaries of the frame and the validity of the samples.

  • start — Indicates the start of the output frame

  • end — Indicates the end of the output frame

  • valid — Indicates that the data on the output data port is valid

For more detail, see Sample Control Bus.
