Is it feasible to create computer-like hardware designed to execute a specific algorithm?
Yes, many algorithms are faster when executed in hardware than in software.

Yes, hardware is faster, because it runs on hardware, not software. However, high end FPGAs are expensive, and custom ASICs are expensive as well. Sometimes it is just cheaper to execute something in software, and it will be cheaper as it does not need dedicated hardware. It all depends on how much you want to pay for making it faster and execute in hardware.


It is done. People buy dedicated hardware for specific tasks, reconfigurable or not. There are CPU chips, there are GPU chips, there are DSP chips, there are video processor chips, audio processor chips, even crypto currency mining chips. FPGA is just a logic chip that can be reconfigured for certain task, and developing a hard-copy to a implement a specific function as an ASIC chip.
