New Block Library for C6416 DSK Target
The blocks in the C64x DSP Library correspond to assembly-code routines in
the Texas Instruments TMS320C64x DSP library, which target the TI C64x
family of digital signal processors. You use these blocks to develop simulations
by building models in Simulink before generating code. Once you have a model
developed, you can invoke the Real-Time Workshop to generate code that is
optimized to run on the C6416 DSK. During code generation, each
C64x DSP library block in your model is mapped to its corresponding
TMS320C64x DSP library assembly-code routine to create target-optimized
code. The C64x DSP library blocks generally input and output fixed-point data
types. For more information about each block, refer to the block reference page
in the User’s Guide.
The following table lists each block in the C64x DSP library.
