Abstract: Systems or methods of the present disclosure may include a programmable logic device having a first portion of programmable elements configured to implement a user logic. The programmable logic device also includes a second portion of the programmable elements. The second portion is configured to implement an infrastructure processing unit (IPU) to enable the first portion of programmable elements to interface with a plurality of accelerator engines. The IPU is to receive a chained command to cause two or more accelerator engines of the plurality of accelerator engines to perform sequential operations on a data packet in response to the chained command.
