Abstract: In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for presentation of direct accessed storage under a logical drive model; for implementing a distributed architecture for cooperative NVM Data protection; data mirroring for consistent SSD latency; for boosting a controller's performance and RAS with DIF support via concurrent RAID processing; for implementing arbitration and resource schemes of a doorbell mechanism, including doorbell arbitration for fairness and prevention of attack congestion; and for implementing multiple interrupt generation using a messaging unit and NTB in a controller through use of an interrupt coalescing scheme.

Abstract: A method and apparatus to perform Cyclic Redundancy Check (CRC) operations on a data block using a plurality of different n-bit polynomials is provided. A flexible CRC instruction performs a CRC operation using a programmable n-bit polynomial. The n-bit polynomial is provided to the CRC instruction by storing the n-bit polynomial in one of two operands.

Abstract: A method and apparatus is described for processing of network data packets by a network processor having cipher processing cores and authentication processing cores which operate on data within the network data packets, in order to provide a one-pass ciphering and authentication processing of the network data packets.

Abstract: A parallel hardware-based multithreaded processor is described. The processor includes a general purpose processor that coordinates system functions and a plurality of microengines that support multiple hardware threads. The processor also includes a memory control system that has a first memory controller that sorts memory references based on whether the memory references are directed to an even bank or an odd bank of memory and a second memory controller that optimizes memory references based upon whether the memory references are read references or write references.

Abstract: Techniques are described herein to overlay and merge any number of tables of equivalent size and structure. Bits or patterns of bits that are similar among tables may be set to a voltage value representative of respective logical ‘0’ or ‘1’. The bits that are different among the tables may be connected to either the value of a table selection signal or its inverse.

Abstract: A data processing device includes a crypto unit having an alignment buffer for providing data to transmit buffer elements of a media switch fabric in multiples of a predetermined number of bytes. Ciphered data for a packet can be split over first and second transmit buffer elements so as to reduce the amount of software intervention.
