Embedded Target for Texas Instruments C6000 DSPs

About the C62x DSP Library

The blocks in the C62x DSP Library correspond to functions in the Texas Instruments TMS320C62x DSP Library assembly-code library, which target the TI C62x family of digital signal processors. You can use these blocks to run simulations by building models in Simulink before generating code. Once you develop your model, you can invoke Real-Time Workshop to generate code that is optimized to run on the C6711 DSK or C6701 EVM. During code generation, each C62x DSP Library block in your model is mapped to its corresponding TMS320C62x DSP Library assembly-code routine to create target-optimized code.

The C62x DSP Library blocks generally input and output fixed-point data types. The reference pages in Block Reference discuss the data types accepted and produced by each block in the library. Fixed-Point Numbers gives a brief overview of using fixed-point data types in Simulink. For a more in-depth discussion of this topic, including issues with scaling and precision when performing fixed-point operations, refer to your Fixed-Point Blockset documentation.

You can use C62x DSP Library blocks with certain core Simulink blocks, as well as with certain blocks from the DSP Blockset and Fixed-Point Blockset. To learn more about creating models that include both C62x DSP Library blocks and blocks from other blocksets, refer to Building Models.

Common Characteristics

The following characteristics are common to all C62x DSP Library blocks:

• Sample times are inherited from driving blocks.
• Blocks are single rate.
• Parameters are not tunable, except for filter weights and coefficients, and not in real-time.
• All blocks support discrete sample times. Individual reference pages indicate blocks that also support continuous sample times.

To learn more about characteristics particular to each block in the library, refer to Block Reference.
