Abstract: A Solid-State Disk (SSD) controller uses LDPC decoding to enable flash memory accesses with improved latency and/or error correction capabilities. With SLC flash memory having a BER less than a predetermined value, the SSD controller uses a 1-bit read (single read) hard-decision LDPC decoder to access the flash memory. If the hard-decision LDPC decoder detects an uncorrectable error, then the SSD controller uses a 1.5-bit read (two reads) erasure-decision LDPC decoder to access the flash memory. With flash memory having a raw BER between two other predetermined values, the SSD controller omits the use of the hard-decision LDPC decoder and uses only the erasure-decision LDPC decoder to access the flash memory. Variations of the SSD controller similarly access MLC flash memory. Some SSD controllers dynamically switch between hard-decision and erasure-based decoders based on dynamic decoder selection criteria.

Abstract: The present invention is directed to a method of operation of a host system by which the host system obtains a driver necessary for running a device (ex.—peripheral device, such as a USB stick, printer, etc.) connected to the host system in an operating system of the host system. In the method(s) disclosed herein, the driver (ex.—host driver) is embedded within in an on-board memory of the device itself. The host system queries the device to determine if and where within the device the driver is located and uploads the driver from the peripheral device. This promotes improved efficiency since the host does not have to store drivers it may not need, but can just obtain the driver from the peripheral device once the peripheral device is connected to the host.

Abstract: In one embodiment, a cryptography processor compatible with the Advanced Encryption Standard (AES) for encrypting and decrypting has a memory storing each element of an AES State, normally 8-bit long, in a corresponding memory space that is at least 9 bits long. Using the larger memory spaces, the processor performs modified AES transformations on the State. A modified column-mixing transformation uses bit-shifting and XOR operations, thereby avoiding some multiplications and modulo reductions and resulting in some 9-bit State elements. A modified byte-substitution transformation uses a 512-element look-up table to accommodate 9-bit inputs. The modified byte-substitution transformation is combined with a modified row-shifting transformation. The memory has data registers each holding four State elements.

Abstract: A non-linear common coarse delay system and method for delaying a data strobe in order to preserve fine delay accuracy and compensate PVT (Process, Voltage, and Temperature) variation effects. A common coarse delay and a fine delay can be initialized to a quarter-cycle delay for shifting a read output DQS (Data Queue Strobe) associated with a memory device in order to sample a read output DQ (Data Queue) within a physical layer. The fine delay can be programmed from minimum to maximum delay with fixed linear increments at each delay step in order to determine the resolution and accuracy of the delay. An optimum delay size of both the coarse and the fine delay can be determined based on an application slowest frequency of operation. A spare coarse delay and a functional coarse delay can be trained in association with a spare fine delay and the functional fine delay can be updated in order to monitor the process, voltage, and temperature variation effects.

Abstract: A circuit and method are presented for signal processing and routing of digital voice telephony signals, using a specialized high-density integrated circuit voice processor. The voice processor performs several essential functions required for telephony processing, including echo cancellation, protocol conversion, and dynamic range compression/expansion. These functions are traditionally performed by multiple circuits or modules. By combining these capabilities in a single device, power and circuit board area requirements are reduced. The embodiment of the circuit and method disclosed herein include novel implementations of a time-slot interchange circuit and a telephony signaling circuit. Both of these circuits are designed to minimize demands on the signal processing engines incorporated within the voice processor, and account for very little of the on-chip circuitry.

Abstract: Described embodiments process data packets received by a network switch coupled to an external buffering device. The network switch determines a queue of an internal buffer of the network switch associated with a flow of the received packet and determines whether the received packet should be forwarded to the external buffering device. If the received packet should be forwarded to the external buffering device, the network switch sets an external buffering active indicator indicating that the network switch is in an external buffering mode for the flow, tags the received packet with metadata, and forwards the packet to the external buffering device. The external buffering device stores the forwarded packet in a queue of a memory of the external buffering device corresponding to the tagged metadata of the forwarded packet. The network switch processes packets stored in the internal buffer of the network switch.

The method and system uses computer readable code embodied within the controller level of an SAS domain to monitor a plurality of PHY pairs associated as connecting through a wide port. The invention compares a history of PHY pair errors to a tunable timer to determine if PHY errors reach a threshold. Should the threshold be exceeded, the controller disables the error prone PHY pair and delivers a notification. The controller may then re-enable the disabled PHY after user action or port power up.

Abstract: A multiprocessor system with multiple watchdog timers, the timers causing all the processors in the system to concurrently process a common interrupt signal asserted by any of the watchdog timers timing out.
