*5.2.1 Approach to CPU block mathematical model of an aircraft*

The GPU blocks (*Block1*, *Block2*, ..., *Block4*) count and each of them numerically counts only one block of the mathematical model of aircraft motion. According to our solution, the algorithm of the block structured mathematical model of aircraft motion is the most suitable for implementation in a GPU-enabled manner [2, 26].

In proposed solution, CPU system communicates with GPU by means of an SMS. The CPU is designed with fewer processor cores that have higher clock speeds, allowing them to complete series of tasks very quickly. The CPU is the brain of operation that is responsible for providing instructions to the rest of system. On the other hand, a GPU has much larger number of cores and is designed for a different purpose; it has parallel processing architecture that allows it to perform multiple calculations across streams of data simultaneously. The GPU has a massive parallel architecture consisting of thousands of smaller, more efficient cores [26].
