Abstract

A system for an embedded disk controller is provided. The system includes a first main processor operationally coupled to a high performance bus; a second processor operationally coupled to a peripheral bus; a bridge that interfaces between the high performance and peripheral bus; an external bus controller coupled to the high performance bus and operationally coupled to external devices via an external bus interface; an interrupt controller module that can generate a fast interrupt to the first main processor; a history module coupled to the high performance and peripheral bus for monitoring bus activity; and a servo controller that is coupled to the second processor through a servo controller interface and provides real time servo controller information to the second processor. The second processor may be a digital signal processor that is operationally coupled to the first main processor through an interface.
