The HLS Kernel to AIE block reformats a signal driven by a port of an HLS kernel block, so that the resulting signal matches the data type and complexity required by an AI Engine kernel or an input of a AI Engine graph block. For example, if the data type of port of the HLS kernel block is axiu<128> and the data type of the port of the AI Engine is uint32, the HLS Kernel to AIE block reformats the input samples by unpacking each axisu<128> sample into four uint32 samples. The output port of this block is a variable-size signal.

Output Type
Possible values are: int8, int16, int32, int64, uint8, uint16, uint32, uint64, cint16, cint32.
Output Size
The size of the output port. The output port is a variable-sized signal whose maximum size is specified by the Output Size parameter. Default size is '1'.
