Abstract: A method and circuit for enhancing the performance in a serial ATA interface uses a standard ATA queue automation circuitry that handles all the transmit/receive frame information structure (FIS) operations for ATA queue commands without interrupting the higher-level software and associated hardware, firmware, and drivers. If the standard ATA queue automation circuitry and command queues are not provided, then every FIS operation will interrupt the higher layer application program. The standard ATA queuing automation circuit preprocesses higher layer commands to write into the task file registers before initiating the transport layer for an FIS transmission and provides information regarding the success or failure of a command. Commands to be executed and completion command queues are preferably used to improve the performance further.

Abstract: Apparatus and methods for enabling multiple, unidirectional, virtual connections between a first SAS device and multiple other SAS devices in a SAS domain. An enhanced first SAS device may be substantially simultaneously coupled to each of two other SAS devices through one or more appropriately enhanced SAS expanders to allow substantially simultaneous unidirectional virtual connections from the first SAS device to both of the second and third SAS devices. Each virtual connection is, in essence, a half-duplex connection such that the first device is transmitting information to a second SAS device substantially simultaneous with the first device receiving information from a third SAS device. The enhancements are provided in a manner to allow backward compatibility with current SAS specifications for connectivity among devices not suitably enhanced in accordance with features and aspects hereof (e.g., with legacy devices).

Abstract: Methods and structures for efficiently storing task file information for a significant number of SATA devices coupled to a SATA storage controller. A RAM memory within the SATA storage controller may store task file information for virtually any number of SATA devices coupled to a SAS communication domain. An arbiter and multiplexing logic is coupled to multiple client logic blocks or processes of the controller each operable to control one or more corresponding SATA devices. The arbiter and associated multiplexing logic grants each client process an opportunity to control its corresponding devices by retrieving saved state information from the task file RAM storage.

Abstract: Methods and associated structures for bypassing virtual memory and memory mapping management features provided in a memory controller applied to simpler computing applications. In one aspect hereof, simpler, embedded computing applications may utilize standard memory controllers including cash management and memory component interfacing features but may bypass virtual memory management features within the same memory controller component. Rather, features and aspects hereof intercept memory accesses generated by the memory controller for address translation features and perform simpler address substitution to apply an appropriate translated address to the system bus.

Abstract: Methods and structures for managing connection requests within a SAS controller operating as an initiator device. A SAS initiator device maintains a table of information regarding known SAS devices in the SAS domain. An index value is used by each of a plurality of link layer processing elements in the SAS controller to access information in the table. The index value is fewer bits than the complete eight byte SAS address and the logic to manipulate and compare the index value is therefore simpler than that required to directly manipulate a full SAS address. Further, the information table is shared by each of the link layer processing elements to further reduce complexity from replication of circuits and logic in the SAS controller.

Abstract: The present invention is directed to a method and apparatus of automatic power management control for a Serial ATA interface that utilizes a combination of IOP control and specialized hardware control. The method may include steps as follows. It is determined, preferably based on a value of the Automate bit in a Task File Ram of a Serial ATA interface, whether a Serial ATA device of the Serial ATA interface is being controlled via the IOP or controlled by the specialized Serial ATA automation hardware. When the Serial ATA device is controlled via the IOP, the IOP may decide when to power up/down the Serial ATA interface. When the Serial ATA device is controlled by the specialized Serial ATA automation hardware, the method may proceed as follows. An idle or active condition of a Serial ATA interface utilizing a combination of IOP control and specialized hardware control is then automatically detected.

Abstract: A method and mechanism for managing dynamically allocated memory. Portions of memory which are available for allocation have additional information stored in association with each portion which indicates whether the portion has been previously identified as being prematurely freed. In addition, a checksum is stored with each portion of memory. In response to a request for deallocation of a portion of memory, the portion of memory is not deallocated if it is identified as having been prematurely freed. Otherwise, the a checksum is calculated for the portion and it is freed. In response to an allocation request, a candidate portion of memory is identified for allocation and a checksum is calculated for the candidate portion. If the calculated checksum does not match a checksum previously stored for the candidate portion, the portion is identified as having been prematurely freed and is not returned for allocation.

Abstract: Disclosed is a system using a SAS host controller and SAS expanders to control multiple SATA end devices where the memory contained on the SAS host controller is fixed to ease the cost and power consumption of the SAS host controller device, but where there is an expanded ability to support additional SATA end devices by configuring the allowed native command queue depth to be smaller for each SATA end device, thus allowing more SATA end devices to be supported by a single SAS host controller. An embodiment of the invention has three possible preset configuration states: thirty-two SATA end devices with a native command queue depth of thirty-two; sixty-four SATA end devices with a native command queue depth of sixteen; and one-hundred-twenty-eight SATA end devices with a native command queue depth of eight.

Features and aspects hereof permit selectively allowing and disallowing changes to such impedance control signals as applied to the driver circuits based upon the present state of the bus and/or the present state of signals driven on the bus by the system embodying the features and aspects hereof.

Abstract: The present invention is directed to a method and apparatus of automatic power management control for a Serial ATA device directly attached to a SAS/SATA host controller. In an exemplary aspect of the present invention, it is determined whether a Serial ATA device is directly attached to a SAS/SATA host controller without using a SAS expander. When it is determined that the Serial ATA device is directly attached to the SAS/SATA host controller, an idle or active condition of a Serial ATA interface including the Serial ATA device and the SAS/SATA host controller is automatically detected. When the Serial ATA interface is in an idle condition, idle time of the Serial ATA interface is measured using a power down counter whose frequency is determined by a programmable register based on an input clock. When a power down counter value is equal to a first value, a request for a Partial power state is asserted, and Serial ATA interface is put into a Partial power state.

Abstract: Test circuitry for supporting real-time testing of data exception software may be included on an integrated circuit. The circuitry supports the identification of a data unit or data group other than a next data unit or data group to be transferred in a data sequence and the generation of an erroneous data verification parameter that does not verify the data content of the identified data unit or data group. The identified data unit or group is later transmitted with the erroneous data verification parameter in real-time following the transmission of other data units and/or data groups having valid data verification parameters. In this manner, a data receiver may be tested to verify the detection of a data content error in real-time and the execution of the software or firmware for processing an exception may be verified. Circuitry for implementing the method of the present invention may be included on the substrate of an integrated circuit.
