6.1 Software Installation and Concepts

Create a directory for the software (for example,
extract the software into the
efcop_fir
out
Each directory contains the C source file(s) and the files required for program configuration,
Efcopdma.cpu
perform the following operations:
1. Include the C file(s) in the project, as appropriate.
2. Set the DSP56307 EVM as the target DSP (within the EDE pull-down menu,
3. Within the same menu, click on
The application is now ready to compile,
high-level debugger can be launched to run the code on the DSP56307 EVM. The application reads input
samples from existing data files in the
out
application results. However, this process is specific to each application and is therefore further explained
in the relevant sections that follow.
In an FIR filter implementation using the EFCOP, to minimize DSP56300 core intervention, the DMA
controller feeds the input data samples to the EFCOP and retrieves output data samples from the EFCOP.
The DSP56300 core is used only to set the EFCOP and the DMA modes and then to activate them.
