Abstract: Methods and apparatus for performing parity and/or ECC operations are disclosed. An example method includes determining that an opcode is being transmitted on a bus and determining if the transmitted opcode is a memory operation. In the event the transmitted opcode is a memory write operation, the example method includes calculating a parity bit for data associated with the opcode, writing the calculated parity bit to a parity table and writing the data to a memory. The example method also includes, in the event the transmitted opcode is the memory read operation, recovering data from a previously written memory, calculating a parity bit for the recovered data, recovering a previously stored parity bit for the recovered data, comparing the parity bit for the recovered data with the previously stored parity bit and, in the event the recovered data parity bit does not match the previously stored parity bit, providing an error notification.
