Abstract:

A method for delocalizing an error checking on a data in a pipelined processor from the data checked. A first check-data is generated at a first location on a first data. A second location receives the first data and the first check-data. A second check-data is generated on the first data and the first check-data is compared with the second check-data at the second location. A second data is generated from the first data and a third check-data is generated on the second data at the second location. A third check-data is generated on the second data at the second location and the second data is transferred to a third location. The third check-data is transferred to a fourth location. A fourth check-data is generated on the second data and is transferred to the fourth location. The fourth check-data and the third check-data are compared at the fourth location.
