Performance Analysis of Multiplication and Addition of High-performance Block Matching Circuit
-
Abstract
The image matching based on normalized cross-correlation has been widely applied in navigation guidance and pattern recognition,because of the large amount of calculation,the application of the hardware implementation is normally used.There's a comparative analysis between the two typical structural circuits Cascade accumulation and Concurrent accumulation on computing time performance and resource utilization.So as to make clear how to pick over a circuit to complete the calculation according to the concrete matched sizes,which help to obtain a better realtime performance and better resource utilization.At the end,there's an explanation on storage model from the perspective of data reuse.And it gives out the computing method of the bandwidth of computing kernel in the end.
