Fixed-Point Code Generation of Product, Sum, and
Gain Blocks
The built-in Simulink™ blocks Gain, Product, and Sum now generate code
specifically for fixed-point code generation. This adds more support for
generating true fixed-point capable code from the Embedded Target for TI
C6000 DSP.
Support for Adding DSP/BIOS™ to Projects
With this release, you can generate code that incorporates DSP/BIOS™
modules and the DSP/BIOS API. Adding the DSP/BIOS functionality lets you
take advantage of the modules and tools in DSP/BIOS to provide
multithreading, real-time analysis, optimization, and other instrumentation in
your Code Composer Studio™ (CCS) projects and executable files. For more
information about adding DSP/BIOS to your generated code, refer to “Using
DSP/BIOS” in the Embedded Target for TI C6000™ DSP User’s Guide.
ADC and DAC Block Requirement Removed
By adding a scheduler to the target software (synchronized to the clock on the
board), we have eliminated the requirement that you include at least one ADC
or DAC block in the models you develop for targeting. When your model does
not include the ADC or DAC blocks, the new scheduler provides the interrupts
to trigger events in your model instead of relying on the DMA on the board.
