摘要:
The present invention relates to a method and apparatus for performing motion adaptive frame averaging for ultrasound color flow images used to overcome lag and smearing alias of color due to motion. One embodiment of the present invention comprises an ultrasound machine for generating an color flow imaging responsive to moving tissue. The ultrasound system comprises a front end and at least one processor. The front-end is arranged to transmit ultrasound waves into the moving tissue, generating received signals in response to the ultrasound waves backscattered from the moving tissue. The processor is responsive to the received signals, calculating a motion factor by comparing at least one current b-mode frame with at least one previous b-mode frame, determining motion using at least the motion factor, increasing a level of frame averaging if the motion factor is below a first predetermined threshold, and decreasing the level of frame averaging if the motion factor is above a second predetermined threshold.

The present invention relates to a method and apparatus providing tissue harmonic imaging using an ultrasound machine. Coded pulses and the phase inverted version of the said coded pulses with time bandwidth greater than 1 are transmitted into the tissue. Backscattered echoes are received and filtered before or after coherent summation. Decoding/compressing of the received echoes of the coded pulses is implemented naturally through the propagation of the specially designed ultrawide band (>80%) waveforms inside tissue and pulse inversion. Costly decoding/compression filter are not necessary.

Technologies for flexible I/O endpoint acceleration include a computing device having a root complex, a soft endpoint coupled to the root complex, and an offload complex coupled to the soft endpoint. The soft endpoint establishes an emulated endpoint hierarchy based on endpoint firmware. The computing device may program the endpoint firmware. The soft endpoint receives an I/O transaction that originates from the root complex and determines whether to process the I/O transaction. The soft endpoint may process the I/O transaction or forward the I/O transaction to the offload complex. The soft endpoint may encapsulate the I/O transaction with metadata and forward the encapsulated transaction to the offload complex. The soft endpoint may store responses from the offload complex in a history buffer and retrieve the responses in response to retried I/O transactions. The I/O transaction may be a PCI Express transaction layer packet. Other embodiments are described and claimed.

Generally, this disclosure relates to adaptive interrupt moderation. A method may include determining, by a host device, a number of connections between the host device and one or more link partners based, at least in part, on a connection identifier associated with each connection; determining, by the host device, a new interrupt rate based at least in part on a number of connections; updating, by the host device, an interrupt moderation timer with a value related to the new interrupt rate; and configuring the interrupt moderation timer to allow interrupts to occur at the new interrupt rate.
摘要:
An apparatus which comprises two or more moderation timers associated with an interrupt vector is presented. In one embodiment, the apparatus comprises two or more interrupt vectors and moderation timers are set with different interrupt rates. An interrupt vector logic unit sends an interrupt vector if there is an interrupt event from the queue associated with a moderation timer and the moderation timer expires.
