Design of a digital circuit for controlling an audio system VHDL

hello,

i have a project to do , i think you can help me , sorrry if my english is not good !

Sujet :

Conception d’un circuit numérique pour la commande d’un système audio et son implantation dans un composant FPGA

Plan :

· Etude du composant CODEC

o Structure interne

o Programmation

o Interface externe

· Architecture du circuit de commande

o Fonction :

Il doit réaliser les opérations suivantes :

· Enregistrer (REC)

· Lire (PLAY)

· Passer au ‘morceau’ suivant (FF)

· Revenir au ‘morceau’ précédent (RW)

· Revenir au début

o Conception du système de commande avec VHDL

o Simulation avec le système QUARTUS II

o Implantation dans un composant FPGA

· Etude de l’interface CODEC/Commande

(Réaliser cette interface en se basant sur le bus I2C)

thankx

    The project extent isn't quite clear. The title "commande d’un système audio" sems to refer to the control system only, not the digital audio data path. Nothing is said about audio data storage respectively digital audio signal source.

    the source is a memory flash , and yes its just control system not the whole system

    here is an english version :

    subject:

    Design of a digital circuit for controlling an audio system and its implementation in an FPGA

    plan:

    · Study of the component CODEC

    o Internal Structure

    o Programming

    o External Interface

    · Architecture of the control circuit

    o Function:

    He must do the following:

    · Register (CCC)

    · Read (PLAY)

    · Switch to 'track' according to (FF)

    · Return to 'track' previous (RW)

    · Return to Top

    o System Design with VHDL control

    o Simulation System with Quartus II

    o Implementation in FPGA

    · Study of the interface CODEC / Order

    (Making this interface based on the I2C bus)

    What CODEC are you using? For now you should concentrate on the first part. Get the CODEC datasheet and understand how it is working and how it is controlled.
