LaMeres CPU verilog code for Spartan 7 FPGA
`timescale 1ns / 1ps
// Code was provided by Brock J. LaMeres
// See his book "Introduction to Logic Curcuits & Logic Design with Verilog" (2nd edition)
// for more detailed discussions
//
// It was modified for Spartan7 and pared down for simplicity
// Only 3 instructions LDA, STA, and BRA to demonstrate simple program
// Only a single output port to display result
