Method and system for monitoring embedded disk controller components

摘要

A history module for monitoring plural components in an embedded disk controller with a first main processor operationally coupled to a first bus and a second processor operationally coupled to a second bus is provided. The history module includes an event control module that receives break point conditions that stops the history module from recording information of a component; and a first register that allows selection or-de-selection of certain components in the embedded disk controller. The first register can also store a trigger mode value, which specifies a number of entries that are made in history module buffer(s) after a break point condition is detected.
