Design, Modeling and Implementation of 8-bit Processor for Intelligent Automatic Chocolate Vending Machine (AVM)

Abstract

This paper describes the design, modeling and simulation of an 8-bit dedicated processor for a Chocolate Automatic Vending Machine (AVM). The proposed dedicated processor is modelled by writing appropriate programs in. The system supports 8 different 8-bit instructions. System simulation was carried out using Xilinx ISE Design Suite 14.6. After accepting the user input which is in the form of desired amount (Re.1, 5, 10 or 20) and second input i.e. choice of the chocolate, the system formulates the chocolate using pre-programmed appropriate proportions and vends it automatically to the user. The system would formulate the recipes with embedded logic. Each recipes involves mixture of various other ingredients which finally results in the desired type of chocolate formation. The Chocolate AVM unlike most other vending machines, prepares chocolate instantly. When the entire process is complete, the vending machine should produce the chocolate and return if any change left.
