2LED MATRIX DESIGNING
Introduction
Advancement and innovation in technology has changed the concept of how vision
and display tools are used, their designing methods and techniques. Due to their long lifetime
and small size, LEDs OR Light emitting diodes are good example of efficient and recent
display technology. These light emitting diodes are used for several applications such as
advertisement displays, panel screens and public places. One of the reasons for using LEDs is
due to their precise and high resolution of displaying animated, static and visual information
effectively. Moreover, the LEDs can be synchronized and controlled to show specific
information on a display panel with the help of intelligent circuitry (De Jong 2014). With the
help of the software called MATLAB, image processing can be conducted by converting the
requirements from binary data to the FPGA’s input signal.
Hardware design based on Micro blaze, Vivado and Nexys 4 DDR FPGA board are
used and the assignment will cover validation, system development and vision and image
processing fields in real time. Micro Blaze (an IP core which is software based) is used for
implementation and designing of the registers. The registers will be put into the Xilinx FPGA
(general purpose).
The aim of this assignment is to demonstrate, implement and design an array LED
driver with dimensions of 16X16.
Design specification:
Nexys 4 DDR:
This is based on the Artix-7 FPGA (Field Programmable Gate Array). From complex
EE (Embedded electronics) processor to simple combinational circuits, this offers many
