Connections between an output port of an AI Engine kernel and an input port of an HLS kernel use an AIE to HLS
kernel block. Connections between an output port of an HLS kernel and an input port of
an AI Engine kernel use an HLS to AIE kernel block.
These blocks reformat the data to match the data type of the the sink port. In this
process no data (information) is lost; and it is simply adjusting the data type and the
number of samples. For example, an interface block can reformat a signal carrying 64
int8
values to a signal carrying 16 int32
values.
These blocks are availebl in the Xilinx Toolbox/AI Engines/Interfaces library.
