Abstract
A system and method for an embedded disk controller is provided. The embedded disk controller includes a main processor in communication with a first bus. A second processor communicates with a second bus. An external bus interface controller ('EBC') located on the embedded disk controller manages a plurality of memory devices external to the system embedded disk controller via an external bus interface and coupled to the first bus and an external bus. Each of the plurality of memory devices has at least one of different timing characteristics and different data widths. The EBC is coupled to the first bus and stores at least one of a segment descriptor register and at least a device range register.
