Onboard computing environment of autonomous unmanned underwater vehicles: possible design technologies and their comparative analysis

Abstract

The paper considers the main tasks of autonomous unmanned underwater vehicles (AUV), lists the requirements for the onboard computing environment. Comparative analysis of central processing unit (CPU), graphics processing unit (GPU), field-programmable gate array (FPGA) and application‐specific integrated circuit (ASIC) has been carried out. The FPGA was considered in more detail as the basis of the AUV onboard computing environment. The given example of designing a device that calculates an arithmetic function demonstrates the high performance of an FPGA and the complexity of developing a simple device in comparison with a similar task on a CPU.
