摘要:
Systems, apparatuses, and methods for an interface module to interface with an enclosure services processor are described herein. The interface module may include one or more state machines configured to provide an enclosure service operation. Provision of this enclosure service operation may be at least partially unsupervised by a control processor requesting the enclosure service operation. Other embodiments may be described and claimed.

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.

A novel partitioned parity check and regeneration circuit is provided for receiving an input data word which is partitioned and the partitioned bits are stored in a partitioning register to provide a subset input data word of fewer data bits than the input data word. Parity register means including a parity register are associated with the partitioning register to provide a parity check of the partitioned data word and for generating an error detect signal when the data bits in the partitioning register are not properly latched. The parity bits stored in the associated parity register are employed with associated output logic to generate regenerated parity bits associated with the output of the data bits in the partitioning register to preserve the integrity of the data.
