Incomputing,Machine Check Architecture (MCA) is anIntel andAMD mechanism in which theCPU reports hardware errors to theoperating system.
Intel's P6 and Pentium 4 family processors,AMD's K7 and K8 family processors, as well as the Itanium architecture implement a machine check architecture that provides a mechanism for detecting and reporting hardware (machine) errors, such as: system bus errors,ECC errors, parity errors,cache errors, andtranslation lookaside buffer errors. It consists of a set of model-specific registers (MSRs) that are used to set up machine checking and additional banks of MSRs used for recording errors that are detected.[1]
