OUT-OF-CYCLE ERROR CORRECTION APPARATUS

摘要

The method and device are for correcting errors in data processing systems to enable the introduction of error-free data groups into the instruction buffer of the execution control register of a system with a clock generator. Error detection and correction devices within the central processing unit handle data groups transferred from the control register to the execution buffer. A first set of devices access the data groups in the register and apply them to the instruction buffer and error detector and correction devices. If a correctable error is detected a second set of devices supplies corrected data to the buffer.
