Abstract: An apparatus for determining one or more elements or compounds in a laboratory sample, and for simultaneously performing both vapor generation and nebulization in one device, is disclosed. The apparatus comprises an enclosed cyclonic spray chamber with two integrally affixed cylindrical ports, one for introducing a nebulizer into the chamber and the other for facilitating volatilization of analytes within the chamber. In addition, two conical tubes are integrally affixed to the chamber and oriented opposite each other, with one tube serving as the means for introducing a sample into the spray chamber, and the other tube serving as the means for introducing reductant/reactant into the spray chamber. This invention allows a sample that has been introduced into the spray chamber to be subjected to nebulization or vapor generation, or to both processes.

Abstract: The compilation of a high-level software-based description of an algorithm into efficient digital hardware implementation(s) is addressed. This is done through the definition of new semantics for software constructs with respect to hardware implementations. This approach allows a designer to work at a high level of abstraction, while the semantic model can be used to infer the resulting hardware implementation. These semantics are interpreted through the use of a compilation tool that analyzes the software description to generate a control and data flow graph. This graph is then the intermediate format used for optimizations, transformations and annotations. The resulting graph is then translated to either a register transfer level or a netlist-level description of the hardware implementation.

Abstract: A method of operating a RAM memory having a plurality of memory addresses for storing data, the method being performed with a timing based on clock signals spaced by clock periods and comprising the steps of: receiving an address and a function signal specifying a function to be performed on data associated with that address; determining whether the same address has been received during a predefined number of preceding clock periods; generating a first data item representing data associated with the received address; modifying the first item according to the function signal to generate a second data item associated with the address, and writing the second data item to the address in the RAM and retaining a separate record of the last n second data items, the step of generating a first data item being performed by: (i) if the result of the determination is negative, generating the first data item to be equal to data stored by the RAM in the address, and (ii) if the result of the determination is positive, gene

Abstract: An apparatus and method for managing reliable datagram work queues, and associated completion queues, using head and tail pointers with end-to-end context error cache are provided. With the apparatus and method, reliable datagram (RD) queue head and tail pointers are maintained in the channel interface and the host channel adapter. The head and tail pointers in the host channel adapter include a RD queue page table index and a RD queue page index for identifying a position within the RD queue. For RD work queues, the tail pointer in the channel interface is used to identify a next position where a work queue entry may be written. The head pointer in the channel interface is used only to determine whether the work queue is full or not. The head pointer in the host channel adapter is used to identify a next work queue entry for processing by the host channel adapter. The tail pointer in the host channel adapter is used by the host channel adapter to determine if the queue is empty.

Abstract: A distributed computing system is provided having (host and I/O) end nodes, switches, routers, and links interconnecting these components. The end nodes use send and receive queue pairs to transmit and receive messages. The end nodes use completion queues to inform the end user when a message has been completely sent or received and whether an error occurred during the message transmission or reception process. A mechanism may implement these queue pairs and completion queues in hardware. A mechanism controls the transfer of work requests from the consumer to the channel adapter hardware using only head pointers in the hardware is described, along with a mechanism for passing work completions from the channel adapter hardware to the consumer using only tail pointers in the hardware. With this scheme the channel adapter hardware can inform the CI that a work request has been completed and provide the work completion information with just a single write to system memory.
