This video dives deeper into the details of the Programmable Real-Time Unit and Industrial Communications Subsystem (PRU-ICSS). The programmable nature of the PRU-ICSS, along with its access to pins, events and all system-on-chip (SoC) resources, provides flexibility in implementing fast, real-time responses, custom peripheral interfaces and the ability to offload tasks from the other processor cores of the SoC. The video also includes a comparison of PRU between different processors. Pseudo code is covered, demonstrating easy and flexible interface between the ADC and PRU for different types of interfaces. Lastly, we will discuss how to achieve simultaneous sampling across multiple ADCs and coherent sampling.
