This block is used to connect an HLS kernel block to AI Engine domain when the datatype or complexities of the ports involved do not match.




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 block.
Note: The inputs to the block must be real and the supported input data types are: int32, int64, x_sfix128, uint32, uint64, x_ufix128.



AIE Input Type
Possible values are: int8, int16, int32, int64, uint8, uint16, uint32, uint64, cint16, cint32,float, cfloat
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'. For example if the input is a vector of size 24, its datatype is uint64, and the output datatype is set to uint8, for each input sample, there will be 8 output samples. As such the Output Size should be set to 8x24=192 or larger.
