Abstract
A character recognition apparatus for recognizing an unknown character having a value at a matrix of discrete locations, comprising a ROM having at least a first plurality of storage locations each containing an address storing location and a reference storing location and storing information relative to a reference character, the ROM responding to a count signal and providing a first address signal and a reference signal, a RAM including a second greater plurality of storage locations each storing a value of the unknown character at a discrete matrix location, the RAM being responsive to the first address signal and providing a data signal corresponding to the value of the unknown character at the address location, a counter and a comparator circuit responding to the data signal and the reference signal and producing an output signal that serves as an indication that the unknown character is not the reference character. In the preferred embodiment, two ROMs and two RAMs are employed to enhance the speed of the apparatus.
