Abstract
This invention is data processing apparatus and method. Data is protecting from corruption using an error correction code by generating an error correction code corresponding to the data. In this invention the data and the corresponding error correction code are carried forward to another set of registers without regenerating the error correction code or using the error correction code for error detection or correction. Only later are error correction detection and correction actions taken. The differing data/error correction code registers may be in differing pipeline phases in the data processing apparatus. This invention forwards the error correction code with the data through the entire datapath that carries the data. This invention provides error protection to the whole datapath without requiring extensive hardware or additional time.
