Patent ID: 8090265

Claim:
A method for configuring a system memory of an optical transceiver, the method comprising: an act of a processing entity in the optical transceiver reading a first configuration entry from a memory configuration table, the first configuration entry defining a set of configuration settings for a first memory segment in the system memory of the optical transceiver, the set of configuration settings for the first memory segment defining whether or not a write to the first memory segment should trigger a processor interrupt, where the memory configuration table includes: a first configuration table, the first configuration table including: a plurality of configuration entries, each of which defines configuration settings for a respective memory segment of a first set of memory segments; and a second configuration table including: a plurality of configuration entries, each of which defines configuration settings for a respective memory segment of a second set of memory segments, wherein the first configuration table includes an index that indexes into the second configuration table; an act of the processing entity determining configuration settings for the first memory segment based on the first configuration entry read; an act of the processing entity configuring the first memory segment based upon the determined configuration settings, wherein a memory segment in the second set of memory segments is smaller than the first memory segment; an act of determining that an original value of the first memory segment has been overwritten by a new value; an act of triggering the processor interrupt based on the set of configuration settings for the first memory segment; and an act of restoring the first memory segment to the original value.
