Abstract: Methods and apparatus for efficient scaling of fabric architectures such as those based on PCIe technology, including up to very large fabrics and numbers of hosts/devices for use in ultra-high performance applications such as for example data centers and computing clusters. In one aspect, methods and apparatus for using Non-Transparent Bridge (NTB) technology to export Message Signaled Interrupts (MSIs) to external hosts are described. In a further aspect, an IO Virtual Address (IOVA) space is created is used as a method of sharing an address space between hosts, including across the foregoing NTB(s). Additionally, a Fabric Manager (FM) entity is disclosed and utilized for programming e.g., PCIe switch hardware to effect a desired host/fabric configuration.

Abstract: Methods and apparatus for improved data movement operations through interconnect fabric. In one embodiment, Non-Transparent Bridge (NTB) technology used to perform data movement operations between a host and multiple peer devices using a DMA (direct memory access) engine and at least one descriptor ring having enhanced descriptor entries. In one implementation, descriptor ring entries include source and destination address information, address translation information, and fabric partition information. In one implementation, a DMA engine is configured directly access host memory and generate data packets using the descriptor entry information. In one embodiment, the descriptor ring is a virtual descriptor ring located on DMA hardware, host memory, or elsewhere in the NT fabric address space, and may be accessed by user processes.

Abstract: Devices, systems and methods are provided for writing, by a plurality of computing resources, to contiguous memory addresses of memory that supports random access, without having to specify actual write addresses of the memory.

Abstract: Intravascular devices and systems include a flexible elongate member having a component configured to detect a physiological condition of a patient when the flexible elongate member is in a vasculature of the patient. The probe may also include a connector junction non-rotatably and permanently secured to the proximal portion of the flexible elongate member. The connector junction may be sized for grasping by a health care provider and for rotation to rotate the flexible elongate member when the flexible elongate member is in a vasculature of the patient. The connector junction may include a slack chamber to accommodate slack in a conductor that may be utilized when the flexible elongate member is introduced through tortious vasculature.

Abstract: Systems and methods are provided for performing write-with-response operations in a network on a chip architecture. In response to receiving an instruction to perform a write-with-response operation, a writer computing resource of a computing system (implemented using the network on a chip architecture) executes this instruction by performing a write operation for writing data to a memory location followed by a response operation for notifying a notification target computing resource of the computing system that the data has been written to the memory location.

Abstract: Systems and methods to be used by a processing element from among multiple computing resources of a computing system, where communication between the computing resources is carried out based on network on a chip architecture, to send first data from memory registers of the processing element and second data from memory of the computing system to a destination processing element from among the multiple computing resources, by sending the first data to a memory controller of the memory along with a single appended-read command.

Abstract: One aspect of the present disclosure involves a method. The method includes retrieving, from a diagnostic medical device, identification information that identifies a feature of the diagnostic medical device. A proprietary signal is generated in response to the identification information. The proprietary signal is sent to a medical measurement system to facilitate an unlocking of one or more programs to be executed on the medical measurement system. Another aspect of the present disclosure involves a method. The method includes detecting, through an electronic interface device, a coupling of a remote diagnostic medical device. Thereafter, a proprietary signal is received from the electronic interface device. An identity feature of the remote diagnostic medical device is ascertained based on the proprietary signal. One or more programs are unlocked for execution if the identity feature of the remote diagnostic medical device matches a predetermined identity feature.

Abstract: Cardiac stroke volume (SV) of a subject is estimated as a function of a value derived from a measured arterial pressure waveform. The value may be the standard deviation, or a function of the difference between maximum and minimum pressure values, or a function of either the maximum value of the first time derivative or the absolute value of the minimum of the first time derivative of the pressure waveform, or both, or a function of the magnitude of one or more spectral components of the pressure waveform at a frequency corresponding to the heart rate. Cardiac output is then estimated as the product of the subject's heart rate and SV, scaled by a calibration constant. Arterial pressure may be measured invasively or non-invasively.
