  • Patent number: 8583984
    Abstract: A method and apparatus to enable data integrity checking of a block of data while the block of data is being transferred from a volatile memory to a non-volatile storage device is provided. The data integrity checking is performed in conjunction with Direct Memory Access operations and Redundant Array of Independent Disk (RAID) operations. In addition, data integrity checking of syndrome blocks in the RAID is performed during transfers to/from the storage devices in the RAID system and during RAID update and RAID data reconstruction operations.

  • Patent number: 8352764
    Abstract: In one embodiment, the present invention includes power control logic for squelch detection circuitry to enable selective enabling of one or more squelch detection circuits of an interconnect interface in a low power mode. The logic may include a squelch mode control register to select a first mode or a second mode of power control, a second register coupled to the squelch mode control register to receive software settings to indicate which squelch detect circuit(s) to disable in a low power state of the interconnect, and a detector to dynamically detect a logical lane zero of the interconnect in the second mode. Other embodiments are described and claimed.

  • Patent number: 8347011
    Abstract: A system, method and apparatus for prioritizing transactions is disclosed. I/O devices may generate transactions with a stream identifier. A transaction classifier may assign a priority to a transaction based upon a stream identifier of the transaction. An arbiter may select a transaction for processing based upon priorities assigned to the transaction.

  • Patent number: 8275560
    Abstract: A method and system to enable power measurements of a system-on-chip in various modes. In one embodiment of the invention, the system-on-chip has full controllability of its logic and circuitry to facilitate configuration of the system-on-chip into a desired mode of operation. This allows hooks or interfaces to access the system-on-chip externally for measurements. For example, in one embodiment of the invention, the hooks in the system-on-chip allow a backend tester to configure the system-on-chip into various modes easily to perform power consumption measurements of one or more individual components of the system-on-chip. The power consumption measurement of the individual components in the system-on-chip can be performed faster and can be more accurate. In addition, the overall yield of the SOC can be increased as it is easier to detect failure parts.

  • Patent number: 8122265
    Abstract: In some embodiments, a chip includes a scheduler, transmitters, receivers, and control circuitry. The schedule schedules signals to be transmitted outside the chip and the transmitters transmit the scheduled signals outside the chip. The receivers receive signals including signals with temperature information related to a temperature outside the chip. The control circuitry selectively limit a number of commands that can be scheduled within a series of smaller windows while checking the temperature information near the conclusion of a larger window comprising many smaller windows. Other embodiments are described.
