Consistency checking over internal information in an optical transceiver
First Claim
1. In an optical transceiver system including system memory and a consistency checker component, the system memory including a plurality of consistency check portions that are to be subjected to consistency checking and plurality of non-consistency check portions that are not to be subjected to consistency checking, wherein the plurality of non-consistency check portions are interleaved between the plurality of consistency check portions, a method for the consistency checker component to check portions of system memory for consistency, the method comprising:
- during operation of an optical transceiver system, performing;
an act of determining that consistency checking is to be performed on one or more consistency check portions of the system memory;
an act of the consistency checker component reading at least one of the one or more consistency check portions of the system memory that are to be subjected to consistency checking; and
an act of the consistency checker component determining whether or not the data from the at least one of the one or more consistency check portions of system memory is consistent with an expected consistency check value.

Abstract
A method that enables an optical transceiver to perform consistency checking, such as Cyclic Redundancy Checking (CRC), over internal information stored in the transceiver'"'"'s memory while the transceiver is in operation. The optical transceiver includes a system memory and a consistency checker component. The consistency checker component determines that consistency checking is to be performed and identifies which portion of the system memory is to be checked. The consistency checker reads the portion of system memory and determines whether or not the portion of system memory is consistent with an expected consistency check value.

10. An optical transceiver comprising:
-
a system memory, the system memory including a plurality of consistency check portions that are to be subjected to consistency checking and plurality of non-consistency check portions that are not to be subjected to consistency checking, wherein the plurality of non-consistency check portions are interleaved between the plurality of consistency check portions; a consistency checker component for performing consistency checking on one or more of the consistency check portions of system memory, wherein the consistency checking comprises, during operation of the optical transceiver; determining that consistency checking is to be performed on one or more consistency check portions of the system memory; reading at least one of the one or more consistency check portions of the system memory that are to be subjected to consistency checking; and determining whether or not the data from the at least one of the one or more consistency check portions of system memory is consistent with an expected consistency check value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
