    摘要: A method and apparatus for detecting address range overlaps. According to one embodiment, a first mask is generated for a first address range and a second mask is generated for a second address range. A first AND operation is performed on the first address range and the second mask to output a first temporary value. A second AND operation is performed on the second address range and the first mask to output a second temporary value. The first temporary value is then compared to the second temporary value to detect an overlap between the first address range and the second address range. According to an alternate embodiment, a first mask is generated for a first address range and a second mask is generated for a second address range. The first mask is then compared to the second mask to detect an overlap between the first address range and the second address range.

    摘要: A scheduling unit is described for scheduling an execution order of a first instruction of a first type and a second instruction of a second type in an instruction stream where the second instruction precedes the first instruction. The scheduling unit comprises a table that records address component identifiers corresponding to the second instruction. An address comparator is coupled to the table. The address comparator compares address component identifiers that corresponds to the first instruction with address component identifiers on the table. The scheduling unit schedules the first instruction to be executed ahead of the second instruction when the address component identifiers differ from the address component identifiers on the table.

    摘要: The quality of ping-based ultrasound imaging is dependent on the accuracy of information describing the precise acoustic position of transmitting and receiving transducer elements. Improving the quality of transducer element position data can substantially improve the quality of ping-based ultrasound images, particularly those obtained using a multiple aperture ultrasound imaging probe, i.e., a probe with a total aperture greater than any anticipated maximum coherent aperture width. Various systems and methods for calibrating element position data for a probe are described.
