A Study on FPGA Design for Rotating LED Display Available Video Output

LED brightness control for video display application

The technique is suggested for a kind of pulse-width-modulation LED dimming in LED video displays. The significant increase of the gray levels number and image refresh frequency can be achieved when the large number of LEDs is controlled serially. The need for a large number of grayscale levels and high refresh rate is explained. The controlling data flow and the amount of buffer memory are the...

Optimized design for controlling LED display matrix by an FPGA board

The very important objective of the digital designer when using discrete gates for implement a Boolean function is to keep the number of used gates to a minimum and win a memory space without lost the original information. In this sense, the Simplification is very important and could be achieved by a purely algebraic process, but it can be tedious when it arrived to a very large number of varia...

The Power Saving Low Cost Rotating 8 Led Information Display

This paper explains the project which is a special kind of circular rotating 8 LED display. With the help some mechanical assembly, LED count, hardware requirement, and hence overall cost is cut to very affordable price and power is also saved. Also, maintenance and repairing of the display is so easy, that anyone having a little electronics knowledge can take care of this. All the synchronizin...

Design and implementation of an FPGA-based multiple-colour LED display board

An Efficient LUT Design on FPGA for Memory-Based Multiplication

An efficient Lookup Table (LUT) design for memory-based multiplier is proposed.  This multiplier can be preferred in DSP computation where one of the inputs, which is filter coefficient to the multiplier, is fixed. In this design, all possible product terms of input multiplicand with the fixed coefficient are stored directly in memory. In contrast to an earlier proposition Odd Multiple Storage ...
