Supported DSP System Toolbox Blocks with Ne10 Library for ARM Cortex-A Processors

DSP System Toolbox™ Simulink^® blocks you can use with the Embedded Coder^® Support Package for ARM^® Cortex^®-A Processors require specific conditions to allow code replacement with the Ne10 library. You use this code replacement when generating C code from a model or from MATLAB^® code. The Ne10 library supports these DSP blocks only when you set specific properties, as indicated in the following table:

DSP Block	Input Requirements	Parameter Requirements	Equivalent Ne10 Functions
Discrete FIR Filter	Real values (output must also be real values). Single channel (one column). `single` data type.	Filter structure: `Direct Form` or `Lattice MA`. Input processing: `Columns as channels (frame based)`. Initial states: `0`. Coefficient source: `Dialog parameters` or `Input port`.	`'Direct Form'` structure `ne10_fir_init_float` `ne10_fir_float_neon` `'Lattice MA'` structure `ne10_fir_lattice_init_float` `ne10_fir_lattice_float_neon`
FIR Decimation	Real values (output must also be real values). Single channel (one column). `single` data type.	Coefficient source: `Dialog parameters`. Filter structure: `Direct Form`. Input processing: `Columns as channels (frame based)`. Rate options: `Enforce single-rate processing`. Allow arbitrary frame length for fixed-size input signals: Clear the parameter.	`ne10_fir_decimate_init_float` `ne10_fir_decimate_float_neon`
FIR Interpolation	Real values (output must also be real values). Single channel (one column). `single` data type.	Input processing:`Columns as channels (frame based)`. Rate options: `Enforce single-rate processing`. Coefficient source: `Dialog parameters or Input port`.	`ne10_fir_interpolate_init_float` `ne10_fir_interpolate_float_neon`
FFT	Real or complex values. Single channel. `single` data type. Input length must equal FFT length.	FFT implementation: `Radix-2`. Scale result by FFT length: Off (check box is cleared). Inherit FFT length from input dimensions: Check box selected (inherit from input) or check box is cleared (specified in FFT length property). FFT length: Power of 2. Minimum length is 4 when input is complex. Minimum length is 8 when input is real.	`ne10_fft_alloc_c2c_float32` `ne10_fft_c2c_1d_float32_neon` `ne10_fft_alloc_r2c_float32` `ne10_fft_r2c_1d_float32_neon` Wrapper functions, each with an `mw_` prefix, are provided to bridge the library interface.
IFFT	Complex values. Output can be complex or real values. Single channel. `single` data type. Input length must equal FFT length.	FFT implementation: `Radix-2`. Divide output by FFT length: On (check box is selected). Inherit FFT length from input dimensions: Check box selected (inherit from input) or check box is cleared (specified in FFT length property). FFT length: Power of 2. Minimum length is 4 when input is complex. Minimum length is 8 when input is conjugate symmetric.	`ne10_fft_alloc_c2c_float32` `ne10_fft_c2c_1d_float32_neon` `ne10_fft_alloc_r2c_float32` `ne10_fft_c2r_1d_float32_neon` Wrapper functions, each with an `mw_` prefix, are provided to bridge the library interface.
