Blocks That Do Not Show Speed Improvements

The Simulink Accelerator speeds up execution only of blocks from Simulink and the Signal Processing Blockset. Further, the Accelerator does not improve the performance of some blocks in Simulink and the Signal Processing Blockset. The following sections list these blocks.

User-Written S-Function Blocks

In addition, the Accelerator does not speed up user-written S-Function blocks unless you inline them using the Target Language Compiler and set SS_OPTION_USE_TLC_WITH_ACCELERATOR in the S-function itself. See Controlling S-Function Execution for more information.
