FPGAs are LSIs that can be used to create circuits (logic circuits) over and over again.

• Program processing in nanoseconds (one billionth of a second) is possible with very low latency.
• High-speed processing is possible by parallelizing circuits.

These advantages make it ideal for audio conversion and signal processing, where the same process is repeated over and over again, which would be costly with a normal CPU.

SoC FPGA (System on a Chip FPGA) is an FPGA that includes CPU and memory inside and can be implemented on a single chip.

OS porting (optimization) and driver development are also required.
