摘要： Methods and structure for redirecting writes in Redundant Array of Independent Disks (RAID) systems are provided. One exemplary embodiment is a RAID controller that includes a memory and a control unit. The memory is able to store mapping information that correlates Logical Block Addresses of a RAID volume with physical addresses of storage devices. The control unit is able to generate a request to write volume data to at least one of the physical addresses, to determine that a storage device has failed to complete the request, to alter the mapping information by correlating Logical Block Addresses for the request with physical addresses of a spare storage device, to redirect the request to the spare storage device, and to rebuild remaining Logical Block Addresses that are correlated with the storage device that failed.

摘要： A method for system for dynamic channel Log Likelihood Ratio (LLR) quantization for a Solid State Drive (SSD) controller is a targeted approach to scaling which results in a scaled, quantized set of LLRs whose relative magnitude remains undisturbed from an original magnitude. The method reads a set of voltages from each channel of the SSD. The set of reads is configured in location and number for performance. Once a set is returned, the method determines an LLR for each of the voltages read resulting in a raw set of LLRs. Targeted scaling results in a scaled set of LLRs between an upper limit and a lower limit determined for reading by a decoder. Once scaled, the LLRs are rounded and quantized for use by the decoder to produce an Error Correction Code (ECC).

摘要： An image processing system comprises an image processor having image processing circuitry and an associated memory. The image processor is configured to identify a region of interest in an amplitude image, to detect one or more relatively low gradient regions in the region of interest, to reconstruct depth information for said one or more relatively low gradient regions, to extend the reconstructed depth information beyond said one or more relatively low gradient regions to additional pixels of the region of interest, and to generate a depth image utilizing at least portions of the reconstructed depth information and the extended reconstructed depth information. The image processor in some embodiments is adapted for coupling to an active lighting image sensor, such as an infrared sensor that does not provide depth information corresponding to the amplitude image, or an SL or ToF sensor that provides depth information corresponding to the amplitude image.
