Embedded Target for Texas Instruments C6000 DSPs

Creating DSP Application Models for Targeting

Create your real-time model for your application the way you create any other Simulink model--by using standard blocks and C-MEX S-functions. Select blocks to build your model from any of the following sources:

• Use the ADC, DAC, and LED blocks from libraries in the C6000lib block library to handle input and output functions for your target hardware
• Use blocks from the TI C62x DSP Library in the C6000lib block library to build fixed-point models
• Use blocks provided with the Real-Time Workshop
• Use blocks from the DSP Blockset
• Use discrete time blocks from Simulink
• Use blocks from any other blockset that meet your needs and operate in the discrete time domain

Using Logging in Your DSP Applications

Simulink offers various data logging capabilities in the Simulation Parameters dialog for your model. Found on the Workspace I/O pane of the Simulation Prameters dialog, the implicit logging options let you specify how and when Simulink logs model operations and gets data from your workspace.

When your model is running on the target, it cannot communicate directly with MATLAB. Configuration options that tell your model to send or retrieve data from your MATLAB workspace do not work and use processing time to no benefit.

To avoid these effects, do not enable options on the Workspace I/O pane in the Simulation Parameters dialog in your model.

To Turn Off Logging in Your Model

Follow this procedure to disable the logging options in your existing Simulink model.

1. Select Simulation->Simulation Parameters... from the menu bar in your model.
2. Click Workspace I/O to open the Workspace I/O pane.
3. Clear the options in the Load from workspace and Save to workspace fields.
• Input
• Initial state
• Time
• States
• Output
• Final states

Instead of using the Workspace I/O options in Real-Time Workshop to eliminate logging during code generation and operation, run

• dspstartup
  

from your MATLAB command prompt before you create new Simulink models. Running dspstartup disables the Workspace I/O options in the Simulation Parameters dialog for your new models.
