FPGA

An integrated circuit that can be configured by the user after manufacturing to implement custom digital logic. FPGAs contain an array of programmable logic blocks and interconnects that can be reprogrammed to perform different functions. In assistive technology, FPGAs enable the development of custom hardware solutions such as dedicated Braille translators, speech processors, or sensor interfaces that can operate independently of a general-purpose computer, offering advantages in speed, portability, and power efficiency for embedded accessibility devices.
