Windows I/O connections between kernels were deprecated in the 2023.2 release of the AMD Vitis™ software platform. The AI Engine Kernel and Graph Programming Guide (UG1079) describes how the source code of a design should change to upgrade it to buffer I/Os. The following figures show the steps required (repeated for every kernel) to upgrade I/O connections from Windows to buffers.
Make the changes shown in the following figure in the
kernel.ccfile:If the design uses classes, upgrade the associated header file.
In the graph file, modify the connection type and specify dimension. Note division by 4 to convert from bytes to samples.
