So, how exactly do we adapt the familiar 2-D convolution to 1-D or 3-D? The mechanics of sliding filters to compute weighted sums (the definition of convolution) remain the same. We only change how we move the kernel. In this tutorial, we’ll explore the conceptual similarities and dif...

An example image-processing application based upon two-dimensional convolution is described and the operating procedures of custom computing machines are presented. Also presented are the details of directly implementing two-dimensional convolution in a straight-forward, systolic fashion in reconfigurable ...
The characteristics of 2-D convolutions with big kernel in low-rank are analysed, and a fast algorithm is given. Then a systolic array implementation, which is derived by a three-stage dependence-graph-based mapping approach, is presented. It is shown that the architecture has a high efficien...

In real-time ultrasonic 3-D imaging, in addition to difficulties in fabricating and interconnecting 2-D transducer arrays with hundreds of elements, there are also challenges in acquiring and processing data from a large number of ultrasound channels. The coarray (spatial convolution of the transmit...
