FPGA (Field Programmable Gate Array) and ARM processor are two different types of hardware platforms.
FPGA: Field Programmable Gate Array
FPGA is a reconfigurable hardware device that allows users to design custom digital circuits. It consists of a series of programmable logic blocks connected by a reconfigurable interconnect network. FPGAs are very flexible and can be programmed to perform almost any digital function.
ARM Processor
ARM processors are general-purpose processing units based on the ARM architecture, used in embedded systems, smartphones, IoT devices, and even some servers.
