What is the current behavior?

• None

What is the new behavior?

• Conv in time can apply the Conv1d in the time dimension instead of the position dimension applied by the original convolution layer. The kernel size determines the delay time of the module. Specifically, for a kernel size of K, the delay time is K-1, i.e., after K-1 time steps, the module will output the correct result sequentially.

Does this introduce a breaking change?

• Yes
• No

Supplemental information

The test code is located in the bottom comment of the /src/lava/proc/conv_in_time/process.py file.

@zeyuliu1037 Thanks for the contribution. These are missing organized unittests. Lets add unittests in similar hierarchy as tests/lava/proc/conv/
