The proposed architecture is divided into two parts, the
data path unit (DU) and the control unit (CU). Fig. 2
displays the top-level view of the proposed hardware
architecture for Prewitt edge detection.
A 64 K bytes external memory device is used to store the
image pixel values. First, MatIab software read the raw
image pixels and stores it into a memory initialization file
(mit).
Fig. 3 shows the architecture design of the memory pointer
unit (MPU), extemal memory and delay line.
