摘要： A method and apparatus are disclosed for implementing STP flow control in SAS expander devices. SAS expanders are commonly used within a SAS network topology to allow multiple disk drives to connect to multiple host devices. Connections to a SATA HDD are supported using SATA Tunnelling Protocol (STP), which allows SATA traffic to be carried over a SAS network topology. Flow control in a STP connection is applied through a set of special SATA primitives, both for forward and backward flow control. A method is described herein in which STP flow control is supported without the use of a SATA link layer state machine. This allows STP flow control to be terminated on a hop-by-hop basis without knowing the data channel direction or maintaining a SATA link state machine, and while minimizing gate count.

摘要： A multi-port switch and a method of command switching using such a switch. Multiple virtual targets provide multiple hosts with access to the physical target device attached to the target interface of the switch. The switch intelligently dispatches operations received by the virtual targets to the physical storage target device to provide shared access. In doing so, the communication between the switch and the physical target can fully comply with the SATA protocol without the physical target being aware that the operations have originated from multiple physical hosts, and without the multiple physical hosts being aware of the shared nature of the physical SATA target device.

摘要： Broadcast primitive filtering in a SAS expander using virtual domains. The virtual domains can be non-overlapping or overlapping logical subsets of the physical topology, or a logical construct based on the membership of a device within a group. Broadcast event propagation is handled in accordance with predetermined policies associated with the virtual domains. These policies can, for example, include limiting the broadcast traffic within the boundaries of the logical zones defined by the subsets, or routing the broadcast events in accordance with access policies, or privileges, associated with the group.

摘要： A DMA engine is provided that is suitable for higher performance System On a Chip (SOC) devices that have multiple concurrent on-chip/off-chip memory spaces. The DMA engine operates either on logical addressing method or physical addressing method and provides random and sequential mapping function from logical address to physical address while supporting frequent context switching among a large number of logical address spaces. Embodiments of the present invention utilize per direction (source-destination) queuing and an internal switch to support non-blocking concurrent transfer of data on multiple directions. A caching technique can be incorporated to reduce the overhead of address translation.

摘要： A method and apparatus are provided for routing in an SAS expander for logical zoning. Common SAS topology defined by the ANSI T10 specification only relates to physical topology with multiple end devices, as well as to expander devices and the broadcast handling mechanisms in such physical topologies. The present invention introduces the concept of virtual topologies that can be non-overlapping or overlapping subsets of the physical topology and the routing mechanism that handles the routing issues with the virtual topologies.

摘要： Methods and apparatus for finding a match between a target bit pattern and multiple filter bit patterns. A filter array is created from the filter bit patterns and at least one intermediate array is generated from the filter array. Specific columns of the intermediate arrays are then extracted based on bit values of the target bit pattern. A row by row AND operation is performed on these columns to arrive at a match vector. the match vector identifies which of the filter bit patterns in the filter array match the target bit pattern. The method is implemented by using multiple classifier elements operating in parallel with each classifier element handling multiple filter bit patterns.

摘要： Methods and devices for controlling and managing data flow and data transmission rates. A feedback mechanism is used in conjunction with measuring output transmission rates to control the input transmission rates, changing conditions can be accounted for an excess output transmission capacity can be shared among numerous input ports. Similarly, by using maximum and minimum rates which can be requested from an output port, minimum transmission rates can be guaranteed for high priority traffic while capping maximum output rates for low priority traffic. By combining the two ideas of feedback rate control and placing maximum requestable transmission rates, a more equitable output sharing mechanism arises. The measured output transmission rate is used to control and recalculate the maximum requestable output transmission rate for incoming flows, thereby allowing for changing network and data flow conditions.

摘要： Methods and apparatus for reducing the search space processed by mask matching methods. The search space is reduced by grouping the candidate bit patterns into groups and subgroups that have internal bit agreement between the members. By only applying the mask matching methods to a select number of groups selected by their bit agreement with the target bit pattern, the computation time and memory requirement of the mask matching method is reduced.

摘要： A metal surface treatment liquid recycling system includes a treatment liquid collecting tank, a pre-treatment device, a nanofiltration device and a vacuum distillation device, all of which are connected sequentially. The nanofiltration device includes a feed tank, a first-stage nanofiltration membrane unit, and a second-stage nanofiltration membrane unit. Treatment wastewater in the treatment liquid collecting tank is fed into the pre-treatment device to filter out suspended solids and then enter the feed tank. The wastewater in the feed tank is filtered by the first-stage nanofiltration membrane unit and transformed to a first-stage concentrated waste liquid and first-stage infiltration fluids. The first-stage infiltration fluids are fed into and re-filtered by the second-stage nanofiltration membrane unit and transformed to a second-stage concentrated waste liquid and second-stage infiltration fluids. The second-stage infiltration fluids are evaporated and concentrated by the vacuum distillation device for generation of distilled water and high-concentration acid concentrated fluids.
