Abstract: An apparatus and method are described for performing a low overhead error checking and correction. For example, one embodiment of an electronic circuit comprises: one or more memories to store data or instructions in rows and columns, and to further store row parity data comprising a parity value associated with each row and column parity data comprising a parity value associated with each column; and error checking logic to perform a row parity check to detect if errors exist in any of the rows, wherein if an error is detected in one of the rows, the error checking and correction logic is to perform a column parity check to identify a column in which the detected error occurred; and error correction logic to correct the detected error using the detected row and column identified by the error checking logic.

Abstract: A clock domain separation device and a method for operating the device is provided for separating two clock domains of a bus system in a system-on-chip (SoC). The clock domain separation device is a hardware module that acts as a guarding between the two clock domains that contain either bus end, and is generally applicable with handshake-type bus protocols. The clock domain separation module allows for each clock domain to switch its clock on and off independently from the state of the other clock domains, without risking data loss or protocol violation.
