Abstract:
1. A computer-implemented method for enabling recovery by a register file from detection of a parity error, said method comprising: detecting the parity error associated with at least one register of a first register file and a second register that are associated with a parallel file structure, which comprises a first storage and a second storage respectively coupled to the first register file and the second register file for respectively storing a corresponding first parity value and a corresponding second parity value for each data within each register of the first register file and the second register file; determining which one of the first register file and the second register file contains an offending register and which one contains a non-offending register having data corresponding to the data within the offending register; and executing a repair sequence in response to detecting the parity error and determining the non-offending register, wherein the register file associated with the non-offending register transmits data to the register file associated with the offending register.
