Patent ID: 8265893

Claim:
A digital reordering unit of an ultrasonic system for use in an ultrasonic front-end device, the digital reordering unit receiving a set of ordered parameters that are arranged according to respective channels of the ultrasonic front-end device, the ordered parameters used for processing electrical signals corresponding to the respective channels, comprising: a plurality of stages, each stage comprising a plurality of multiplexers and a plurality of D-type flip-flops (DFFs) coupled thereto correspondingly; wherein inputs of a first stage receive the set of ordered parameters, and wherein outputs of the first stage are provided to inputs of a second stage to selectively reorder the ordered parameters based on changes in scan lines of the ultrasonic system; wherein the set of ordered parameters comprises a set of ordered transmission parameters, wherein the ultrasonic front-end is connected between a probe and a detector and includes a transmission beamformer configured to store the set of transmission parameters corresponding to respective transmission channels, wherein the reordered parameters comprise the transmission parameters, wherein the probe comprises M number of array elements where M is an integer larger than or equal to 1, and wherein each stage comprises M number of 2:1 multiplexers followed with respective DFFs; and wherein the transmission beamformer is configured to provide a control parameter which varies as the scan lines of the ultrasonic system change, wherein each bit of the control parameter controls M 2:1 multiplexers at a corresponding stage, wherein inputs at the first stage comprise the transmission parameters for M transmission channels.
