As stated in the introduction, the L2 level of the Ultrasound Library is composed of the mathematical components needed for the beamformation of the rf-data. Those components, on the other hand of the L1 APIs, are AIE graphs and no longer just single kernels. As introduced in the dedicated section, the AIE graphs are a compositions of AIE kernels presents in L1 library. For these reasons, the level of abstraction is increased with respect to the previous level. Following is an explanation of every component of the L2 library with a connection to the already explained theory to bind the concepts with their actual implementation.
