Abstract: Performing an error recovery in response to determining an uncorrectable error in data stored in the memory system, storing the address of a memory location of the uncorrectable error in an address buffer and performing a recovery procedure for the processor core which may reset the processor core to a known status with correct data. When fetching data from a memory location and if it is determined that the address of this memory location is stored in the address buffer, moving the content of an entire cache line related to the address into a quarantine buffer of the processor core. When detecting an error in the data of the moved entire cache line, triggering a repair procedure for the data of this address which may be a special procedure to repair unrecoverable detected errors in data to be processed by a processor core.

Abstract: A method and a system is proposed for formatting trace arrays contents obtained by capturing trace data within trace arrays using a wrap back window during compression mode within which trace data are stored circularly. Following formatting bits are used: Array Wrap Flag (AWF) bit toggling between two values at each array wrap around when wrap back window is left; Wrap Back Counter (WBC) counting the number of wrap backs within the wrap back window. And the method comprises the steps of determining the number of AWF toggles within the trace array and accordingly unwrap the trace array contents by starting with the row of the trace array contents corresponding to the toggling of AWF and determining a row within wrap back window with WBC toggling and if present unwrap wrap back window by reordering the rows of the trace array contents according to an ascending order of the value from the WBC.
