description: The subject of the graduate qualification work: "The use of real-time coprocessors of the AM335x ARM Cortex-A8 Sitara processor to create non-standard digital interfaces".
This work is devoted to the stability study of real-time coprocessors of the processor family AM335x ARM Cortex-A8 Sitara. Tasks that were solved in the course of work:
1. Study of documentation
2. Choosing a way to work with the BeagleBone Black platform;
3. Preparation of a software platform for future development;
4. Development of program code (implementation of an example on which studies of performance, real-time coprocessor delays will be performed);
5. The study of the stability of the real-time coprocessors (PRU-ICSS) in conditions of intensive interaction on data transfer with the central processor.
As a result, an optimal set of development tools was compiled and a test case was created to calculate the PRU delay. Based on this example, another one was compiled that simulates the intense interaction of a real-time module with a central processor.
According to the results of the experiments, the delay of the coprocessor was determined and the influence of the CPU on it under conditions of its full load was analyzed.
