Abstract

Disk files are used in computer systems to store large amounts of data. Most of the data is very important, and good data integrity should be provided on all data paths to prevent undetected errors. Fig. 1 shows a block diagram of a typical computer system with the traditional error detection schemes. Parity is used on the parallel data bus 5, and a cyclic redundancy check is used on the bidirectional serial data on line 6.
