The detected edges are displayed by combining the
horizontal and vertical edges "(1 ). "
This paper proposes a hardware architecture of Prewitt
edge detection. The input image is limited to 8-bit grayscale
and a frame size of 256 x 256 pixels. Moving window is
limited to 3 x 3 masks. The architecture is targeted for
AItera FPGA using Quartus II and is capable of operating
with a clock frequency of 145 MHz at 550 frames per
second (fps). Verification is through synthesis only with
parameters obtained from simulation on Matlab. By using
the combination of both MatIab and Veri log, it can be easily
import and export data to the designed hardware
implementation to read and display images.
