New features and changes introduced in this version are

Broader Support for the Logging of Simulation Minimums and Maximums and Fixed-Point Autoscaling

An increased number of fixed-point capable Signal Processing Blockset blocks now support the logging of simulation minimums and maximums and autoscaling via the Fixed-Point Settings interface.

Fixed-Point Support for the DCT and IDCT Blocks

The DCT and IDCT blocks now support fixed-point data types.

New Audio File Source and Sink Blocks

The From Multimedia File and To Multimedia File blocks in the Platform Specific I/O > Windows (WIN32) library are new in this release.

Multirate Support for CIC Filter Blocks

The CIC Decimation and CIC Interpolation blocks now support multirate sample-based processing.

Obsolete Blocks

The blocks in the table below are obsolete, although they are currently still shipped with the product, and may be removed in a future version of the Signal Processing Blockset product. We recommend that you use the replacement blocks listed in the third column.

Compatibility Considerations

You can run the Signal Processing Blockset function dsp_links to see if you are using any obsolete blocks in your models. If your models are using obsolete blocks, we strongly recommend that you exchange them for blocks that are currently supported.

To access each replacement block, type the library name listed in the Replacement Block(s) Library column at the MATLAB^® command line.
