1. Description

This example demonstrates how to use FIR Accelerator Driver in Legacy Mode and Auto Configuration Mode(ACM). Two FIR tasks are created each having two channels. The Channels of the first and second tasks have taps/window of 64/1024 and 4096/1024 respectively. The inputs and coefficients are given from the following .dat files : - fir_input_taps_64_window_1024.dat - fir_input_taps_4096_window_1024.dat - fir_coeffs_64.dat - fir_coeffs_4096.dat The Outputs obtained are compared with the MATLAB generated output .dat files : - fir_output_taps_64_window_1024.dat - fir_output_taps_4096_window_1024.dat The accelerator can be operated in Legacy Mode or Auto Configuration Mode(ACM) using static configuration. In ACM,additional features related to interrupts,triggers etc are available. For more information on Auto Configuration Mode(ACM), please refer to Hardware Reference Manual for ADSP-2156x processor and also FIR Device Driver Documentation for ADSP-2156x processor. In this example, the interrupts(Callbacks) for all the channels are enabled when the accelerator is operated in Auto Configuration Mode(ACM).
