Abstract: An apparatus and method for mediating a sequence of transactions across a fabric in a data processing system are implemented. A fabric bridge orders a preceding transaction and a subsequent transaction according to a predetermined protocol. Using the protocol a determination is made whether the subsequent transaction may be allowed to bypass the previous transaction, must be allowed to bypass the previous transaction, or must not be allowed to bypass the preceding transaction. Transactions include load/store (L/S) system memory and L/S to input/output (I/O) device, and direct memory access (DMA) to system memory and DMA peer-to-peer transactions.

Abstract: An automated communications system operates to transfer data, metadata and methods from a provider computer to a consumer computer through a communications network. The transferred information controls the communications relationship, including responses by the consumer computer, updating of information, and processes for future communications. Information which changes in the provider computer is automatically updated in the consumer computer through the communications system in order to maintain continuity of the relationship. Transfer of metadata and methods permits intelligent processing of information by the consumer computer and combined control by the provider and consumer of the types and content of information subsequently transferred. Object oriented processing is used for storage and transfer of information. The use of metadata and methods further allows for automating may of the actions underlying the communications, including communication acknowledgements and archiving of information.

Abstract: A method, system, and apparatus for preventing input/output (I/O) adapters used by an operating system (OS) image, in a logically partitioned data processing system, from fetching or corrupting data from a memory location allocated to another OS image within the data processing system is provided. A hypervisor prevents transmission of data between an input/output adapter in one of the logical partitions and memory locations assigned to other logical partitions during a direct memory access (DMA) operation by assigning each of the input/output adapters a range of I/O bus DMA addresses. The I/O adapters (IOAs) are connected to PCI host bridges via terminal bridges. A single terminal bridge may support multiple IOAs, in which case every terminal bridge has a plurality of sets of range registers, each associated with a respective one of the IOAs to which it is connected. An arbiter is provided which selects one of the input/output adapters to use the PCI bus.

Abstract: A methodology and implementing system are provided in which pipelined read transfers or PRTs are implemented. The PRTs include a request phase and a response phase. The PRT request phase involves a PRT request master delivering to a PRT request target, a source address, a destination address and the transfer size for the data being requested. In the PRT response phase, the PRT request target becomes a PRT response master, i.e. a PCI bus master, and initiates a completion of the transaction that was requested in the originating PRT request. Pipelined read transfers are ordered in accordance with a predetermined processing priority to improve performance and avoid deadlocks.

Abstract: A bus bridge including a buffer pool and steering logic where the buffer pool is organized as a plurality of buffers sets including at least first and second buffer sets and the steering logic is adapted to store transactions originating with a first peripheral device in the first buffer set and transactions originating with a second peripheral device in the second buffer set. Transactions may arrive via a secondary bus, such as a PCI bus, coupled to the bus bridge. The bridge further allows relaxed transaction ordering rules compared to conventional PCI transaction ordering rules by identifying transactions by grant signals and thus allows steering of transactions from the first and second devices to first and second buffer sets respectively. The bridge is suitably adapted for combining or merging two or more transactions within each buffer set. Each buffer set preferably includes one or more buffers for temporarily storing transactions arriving from the secondary bus and bound for a primary bus.

The filter cartridge includes a plurality of filter cells arranged in contiguous and stacked relationship, adjacent filter cells being spaced from one another by spacer rings or gaskets, means being provided to hold the filter cells and spacer rings or gaskets in position to form said cartridge, the cartridge having an elongate central aperture into which filtered fluid may flow.

Abstract: A host bridge having a plurality of pre-defined registers used for injecting errors to a selected device so that other devices are not affected and normal systems operations can continue is disclosed. In accordance with the method and system of the present invention, device select lines from each device are brought into the host bridge individually for determining if an error is to be injected to a selected device. First, a register or a bit in a register in the host bridge is matched against an incoming bus operation for the type of bus operation, a load or a store, to inject the error upon. Next, a register having an initial or random value within the host bridge indicates which occurrence of the operation to inject the error. If the value of the register indicates that an error is to be injected, the load or store operation is delayed by forcing zero byte enables until the device identifier of the selected device may be checked against a device register within the host bridge.

Abstract: A method and apparatus is provided in which I/O data is tagged to identify an ordering of data transfer requests relative to other data transfer requests. Write and Read transaction requests are tagged for ordering relative to previous write requests. Current read and write transaction requests are selectively allowed to bypass earlier write transaction requests which have been temporarily delayed in transfer. In one embodiment, the bypass occurs in a bridge buffer positioned between I/O devices and a system memory. In another embodiment, the methodology is applied where a split read or write transaction includes reserved bits in the attribute fields which are utilized to indicate if the transaction is allowed to bypass previous write transactions.

Abstract: A bus bridge including a buffer pool comprised of a first and a second buffer sets. The first and second buffer sets are associated with first and second peripheral devices respectively. The bridge is configured to receive an interrupt and identify the interrupt source. A buffer set associated with the interrupt source is selected and transactions in the selected buffer set flushed prior to forwarding the interrupt to a processor. The bridge is preferably configured to identify the interrupt source by receiving a first interrupt signal from the first peripheral device and a second interrupt signal from the second peripheral device. Preferably, the bridge is configured to flush the transactions by pushing them into system memory via a primary bus such as a host bus of a processor.

Abstract: A method for evaluating atherosclerosis using M-Mode ultrasound to measure atherosclerotic plaques and their affect on compliance of the arterial walls in peripheral arteries. Movement of the arterial walls is measured during a systolic-diastolic pressure cycle and the intimal medial thickness and the thickness of any atherosclerotic lesions are measured as well. The method measures the distance between the near and far walls of the subject artery and the acoustic impedance of the materials that comprise the individual layers of the arterial walls. To image an artery with M-Mode ultrasound, a transducer head having at least one transmitting element and at least one receiving element is placed against a patient's skin adjacent the peripheral artery to be evaluated. A repeating series of sound pulses are transmitted from the transmitting element into the patient substantially perpendicular to the subject artery.
