Abstract
Error detection circuitry for use in a data processing system which utilizes a programmable logic array for controlling, during a write operating mode, the generation of a write error word by an error register, which write error word is thereupon stored together with the associated data words in a data storage device and for controlling, during a read operating mode, the generation of a read error word, the error register thereupon effectively comparing the read error word with the originally stored write error word to produce a remainder word when an error is present.
