Fixed-Point Blockset

Frame-Based Signals

Most real-time systems optimize throughput rates by processing data in "batch" or "frame-based" mode, where each batch or frame is a collection of consecutive signal samples that have been buffered into a single unit. You can process signals in Simulink as frame-based signals.

Fixed-Point Blockset blocks accept frame-based signals for simulation and code generation, except for the Dot Product and FIR blocks.

The DSP Blockset also supports frame-based processing, and can use blocks from the Fixed-Point Blockset in models that process frame-based signals.

For further understanding of frame-based processing, refer to Working with Signals in the DSP Blockset documentation.

Matrix Signals

The Simulink documentation refers to two-dimensional (2-D) signals as matrices. Simulink blocks can output 2-D signals, which consist of streams of two-dimensional arrays emitted at a frequency of one 2-D array per sample time.

Fixed-Point Blockset blocks support matrix-based signals for simulation and code generation, except for the Dot Product and FIR blocks.

For further understanding of matrix-based processing, refer to "Working with Signals" in the Simulink documentation.
