After the build is complete, you can view the microcode produced by the AI Engine compiler by right-clicking the project in the Explorer view and selecting Open Disassembly View. In the Select Active Core dialog box, select the core (AI Engine). This opens the LST (.lst) file which is microcode that corresponds to the kernel code scheduled to be executed on that AI Engine tile. The kernel code is embedded in the LST file after the main end function. You can select parts of the microcode and cross-probe to the corresponding line in the kernel source file. This allows you to examine the number of cycles taken by specific lines of kernel code and see where further optimizations and efficiencies can be made. In the following image you can see the microcode in the LST file in the center left and the corresponding kernel code file to the right. Clicking in either view shows the corresponding code in the other view.
