Realization virtual electric piano based on VHDL

This program design using VHDL language virtual keyboard. Hammond organ design consists of four modules: play module keyplay, auto play module AutoPlay, check gauges and display module table and frequency module fenpin. Plays modules keyplay under the key key indicates the pitch index_key; auto...

FPGA source audio signal Analyzer

Audio signal through consists of the OPAMP and the resistance of the 50Ohm impedance matching circuit to meet the input impedance 50 Ohm system requirements, calculation of signal power. In order to ensure that this signal is undistorted sampled signals through the cut-off frequency for the 10Khz an...

VHDL-based design and analysis of digital clock

Digital Clock is a digital circuit implementation, minutes, seconds, timing devices, compared with the mechanical clock has a higher accuracy and intuitive, and no mechanical devices, with longer life, so it has been widely use. In principle figure is a typical digital circuit, including combination...

Advanced turbo decoder using vhdl

In information theory, turbo codes (originally in French Turbocodes) are a class of high-performance forward error correction (FEC) codes developed in 1993, which were the first practical codes to closely approach the channel capacity, a theoretical maximum for the code rate at which reliable commun...

Pong game on FPGA

This project implements a pong-game on Altera fpga. The game controller is built on the fpga. Player uses keyboards which are connected to fpga boards to play game. The game is displayed on the VGA screen. All components such as keyboards, VGA screen are controlled by the controller....
