This block is used to connect the AI Engine
domain to the HLS kernel block in cases where the data type or complexity of the ports
do not match.

Description
The AIE to HLS kernel block reformats a signal driven by an AI Engine block so that the resulting signal matches the data type and complexity required by the input of an HLS Kernel block.
Topology
Parameters
- Output Data Type
- Possible values are: cint16, int32, uint32, cint32, int64, uint64, sfix128, ufix128, float, and 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 Output Size is '1'. For example if the input signal to the block is
a vector of size 24 and of
uint16data type and the output data type is set touint64, each output sample will include four input samples. As such the output size must be equal to or larger than 8.
Note:
- The input data type must be one of the following: int8, int16, int32, int64, x_sfix128, uint8, uint16, uint32, uint64, x_ufix128.
- The input can be real or complex, but complex inputs are supported only for int16 and int32.
