Abstract: A data storage subsystem that includes three data storage units, three check storage units, and an array controller coupled to the three data and three check storage units can tolerate failure of any three data and check storage units failures can be occur before data stored on the data storage subsystem is lost. Information is stored on the data storage subsystem as a symmetric Maximum Distance Separation code, such as Winograd code, a Reed Solomon code, an EVENODD code or a derivative of an EVENODD code. The array controller determines the contents of the check storage units so that any three erasures of the data storage units and the check storage units can be corrected by the array controller. The array controller updates a block of data contained in any one of the data storage units and the check storage units using only six IO operations.

Abstract: SA9-91-003 Apparatus and method for implementing a parallelized algorithm for solving the key equation for the decoding of a linear algebraic code. A computational loop has one branching condition that branches into two straight-line loops. One of these executes three multiplication operations and the other executes five multiplication operations, 2t iterations of these two loops being required to decode t symbols in error. These loops are coupled such that during each successive 2t iterations, four multiplication operations are executed simultaneously in pairs, the fifth multiplication operation in said other loop being paired with a multiplication operation in the next iteration of said one loop. During one of the paired multiplication operations an inverse table look up operation is executed, and during another of the multiplication operations an addition operation is executed.

Abstract: Parallel ML processing of an analog signal in a RLL-coded channel in which (1) vectors for a current state of the channel and the next state of the channel are computed using Walsh transform vector coefficients of the analog signal; (2) current state vectors and next state vectors and values of vectors precomputed in analog matched filters are used to generate vector scalar products which are compared against preselected threshold values for generating binary decision outputs that are used in digital sequential finite state machines to generate ML symbol decisions; and (3) ML symbol decisions are fed back and used to subtract the intersymbol interference value of the current state vector from the vector of the next state to transform the next state vector into an updated current state vector.

Abstract: A watermark in the form of an added message is attached to a digital recording so that a significant content of the recording is completely unchanged by the process in the sense that any reader commonly used for such recording will extract from the recording exactly what would have been extracted in the case the added message had not been attached. This is done by hiding the added message in the error correcting code (ECC) for the significant content of the recording.
