Abstract: Embodiments of the present disclosure provide mechanisms for measuring currents flowing in one or more conductor wires. The mechanisms are based on using magnetic sensor pairs arranged within a housing with an opening for the wires, where each magnetic sensor pair can generate a pair of signals indicative of magnetic fields in two different directions. The outputs of the sensor pairs can be used to derive a measure of current(s) flowing through the one or more wires. The use of magnetic sensor pairs that can measure magnetic field in two different directions may enable simultaneous current measurement in multiple wires placed within the opening, improve accuracy of current measurements while relaxing requirements for precise control of the placement of the wire(s), reduce the impact of stray magnetic interference, and enable both AC and DC measurements.

Abstract: Embodiments of the present invention provide for improved timing control in 2-D image processing to maintain a constant rate of fetches and pixel outputs even when the processing operations transition to a new line or frame of pixels. A one-to-one relationship between incoming pixel rate and outgoing pixel rate is maintained without additional clock cycles or memory bandwidth as an improved timing control according to the present invention takes advantage of idle memory bandwidth by pre-fetching a new column of pixel data in a first pixel block of a next line or frame while a new column of an edge pixel block on a current line is duplicated or zeroed out. As the edge pixel block(s) on the current line are processed, the data in the first pixel block of the next line or frame become ready for computation without extra clock cycles or extra memory bandwidth.
Abstract translation: 本发明的实施例提供了二维图像处理中的改进的定时控制，即使当处理操作转换到新的像素像素或一行像素时，仍然保持恒定的提取速率和像素输出。 保持输入像素速率和输出像素速率之间的一对一关系，而不需要额外的时钟周期或存储器带宽，因为根据本发明的改进的定时控制通过预取一个新的像素数据列来利用空闲存储器带宽 在下一行或帧的第一像素块中，而当前行上的边缘像素块的新列被复制或清零。 当处理当前行上的边缘像素块时，下一行或帧的第一像素块中的数据就可以在没有额外的时钟周期或额外的存储器带宽的情况下进行计算。
