The following figure gives an overview of how the data will flow through this example design.
The below table gives a brief overview of all the functionalities involved -
| Name | Type | Functionality |
|---|---|---|
| Interpolator | AIE Kernel | Interpolate using 2 samples by taking in 128 cint16 samples block as input and producing 256 cint16 samples block as an output. |
| Polar Clip | User RTL | Performs threshold detection and clipping. |
| Classifier | AIE Kernel | Does some simple classification as per complex plane and produces plane numbers (from 0 to 3) based on the complex value. |
As mentioned above, there are two AIE kernels communicating with the user RTL block. The AIE kernels have four PLIOs, two being file IOs i.e in_interpolator and out_classifier and the other two being external IOs i.e. out_interpolator and in_classifier responsible for propagating traffic in/out of the AIE kernels from the external process running the user RTL block.
