Note: An example C++ file, run_bitacc_cmodel.c is
included that demonstrates how to call the FFT C model. See this file for examples of using
the interface described below.
The C model is used through three functions, declared in the header file xfft_v9_1_bitacc_cmodel.h :
struct xilinx_ip_xfft_v9_1_state* xilinx_ip_xfft_v9_1_create_state
(
struct xilinx_ip_xfft_v9_1_generics generics
);
int xilinx_ip_xfft_v9_1_bitacc_simulate
(
struct xilinx_ip_xfft_v9_1_state* state,
struct xilinx_ip_xfft_v9_1_inputs inputs,
struct xilinx_ip_xfft_v9_1_outputs* outputs
);
void xilinx_ip_xfft_v9_1_destroy_state
(
struct xilinx_ip_xfft_v9_1_state* state
);To use the model, first create a state structure using the
first function, xilinx_ip_xfft_v9_1_create_state. Then run the model using
the second function, xilinx_ip_xfft_v9_1_bitacc_simulate, passing the state
structure, an inputs structure, and an outputs structure to the function. Finally, free up
memory allocated for the state structure using the third function,
xilinx_ip_xfft_v9_1_destroy_state. Each of these functions is described
fully in the following sections.
