Introduction

This example performs 1D Capon Beamforming tests for 6 instances one after the other. There are 2 test files present in the folder:

"examples/alg/caponBeamforming/testbench"

1. caponDataGenerated6ant128snaps32angles6inst_50deg.bin
2. caponDataGenerated4ant64snaps64angles6inst_-30deg.bin

You can change the input file in the "examples/alg/caponBeamforming/caponbeamforming_test_main.c" code, in the caponbeamforming_test_main() function.

The data is read in the M4 memory from the input files. The Capon Spectrum Output is stored in the structure:

caponBeamformingCfg->hwRes.caponSpectrum

After the algorithm is complete, data validation is performed by comparing source and destination memory, against the reference output. If the equality test is successful, the test was successful.

Supported Combinations

Parameter	Value
CPU + OS	m4fss0-0 freertos
	m4fss0-0 nortos
Toolchain	ti-arm-clang
Boards	xWRL1432-evm
Example folder	examples/alg/caponBeamforming

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run

Sample Output

Shown below is a sample output when the application is run when the input file is caponDataGenerated4ant64snaps64angles6inst_-30deg.bin,
