A system, method and apparatus for compressing and decompressing data. A host processor and host memory are coupled to a block I/O device. The host processor issues compress and decompress commands to the block I/O device in accordance with a high-speed data storage and retrieval protocol. The block I/O device compresses/decompresses the data specified in the compress/decompress command, thus relieving the host processor of performing the compression/decompression and freeing the host processor for other tasks.

A system, method and apparatus for encoding and decoding data. A host processor and host memory are coupled to a block I/O device. The host processor issues encode and decode commands to the block I/O device in accordance with a high-speed data storage and retrieval protocol. The block I/O device encodes the data specified in the encode command, thus relieving the host processor of performing the encoding/decoding and freeing the host processor for other tasks.

A system, method and apparatus for encrypting data. A host processor and host memory are coupled to a block I/O device. The host processor issues encryption and decryption commands to the block I/O device in accordance with a high-speed data storage and retrieval protocol. The block I/O device performs encryption on data specified in the encryption command, thus relieving the host processor of performing the encryption and freeing the host processor for other tasks.

Methods, apparatuses, and data storage devices are provided. Address-mapping data is compressed. The address-mapping data indicates mapping from a logical address to a physical address of a non-volatile memory of a storage device. Error checking and correction (ECC) data for the compressed address-mapping data is generated. The compressed address-mapping data and the ECC data are stored in the storage device.

Systems and methods for managing address-mapping data in memory devices

Systems and methods for operating on a storage device are provided. A storage device command for operating on data stored in a plurality of locations in a storage device is received, with a storage device controller from processing circuitry over a bus. The storage device command is decoded with the storage device controller to identify a plurality of storage device operations associated with the storage device command. The plurality of storage device operations are executed on the data stored in the storage device without transmitting the data over the bus to the processing circuitry.

In one or more embodiments, system(s), method(s), integrated circuit(s), physical layer(s), apparatus(es), System-on-Chip (SoC), various other hardware, computer-readable and/or executable instructions, and/or technique(s) are described that enable a subroutine to release control of a processing entity when the subroutine is incomplete. By so doing, the processing entity may be used by code outside of the subroutine, such as code that needs attention, and/or more-fully utilize its own processing power by being less idle.

Call stack structure for enabling execution of code outside of a subroutine and between call stack frames

In one or more embodiments, system(s), method(s), integrated circuit(s), physical layer(s), apparatus(es), System-on-Chip (SoC), various other hardware, computer-readable and/or executable instructions, and/or technique(s) are described that assist a host BIOS, such as by offloading operations from the host BIOS to a remote entity. By so doing, a BIOS's resources may be conserved or more complex or resource-intensive tasks may be performed than may otherwise be possible for some traditional BIOS.

A method and apparatus uses a flexible buffering scheme in an XOR engine to generate checksums, allowing a user to recover data when a disk drive partly or completely fails. An XOR engine may include three or more arithmetic units and three or more local result buffers, which may be used to generate a combination of any of a 'P' checksum, a 'Q' checksum, and an unmodified copy of the user data, in a single read. The local result buffers and arithmetic units allow the use of multiple Galois field Multiply coefficients so that multiple distinct &#x201c;Q&#x201d; checksums may be generated with only one read of the user data.

A system includes a timer and a control module. The control module: in response to a first request for first data, determines whether the first data is stored in a non-volatile semiconductor memory (NVSM); in response to the first data not being stored in the NVSM, (i) loads the first data from a hard disk drive (HDD) and boots up a computer a first time based on the first data, and (ii) while operating in a learn mode and while loading the first data from the HDD, captures a portion of the first data in the NVSM; in response to the timer indicating an end of a period during which the computer is booted up the first time, ceases the capturing of the first data; and based on the portion of the first data captured in the NVSM during the learn mode, boots up the computer a second time.
