| Abstract: | Firstly,this thesis introduces the basic hardware model of image edge detection.In order to realize the design with faster speed and less logic resources,we analyze the key datapath of FIR model and develop some improvement appoaches.Pipelined schemes with optimal arithmetic logic unit are proposed.At last,we show the simulation result and compare the performance of different scheme with FPGA and ASIC implementation.It shows that our design can meet the need of realtime processing with high throughput of image edge detection. |
