FPGA Based Digital Electronic Education, Data Entry Organization for a Calculator

In this study, an example is presented developed under a Project named FPGA based Digital Electronics Education Project (FPGA_b_DEEP). The Project aims to develop instructive and attractive examples to teach Digital Electronics effectively and faster. In the example developed in this study, a data entry organization part of an 8 bits calculator design is dealt with. The design is prepared by considering students/new designers' knowledge level and divided into four parts for better understanding. The functions implemented in the modules are to code a number or an arithmetic operation to each button, to shift the numbers to left side with each entered digit of number, to multiply the digits with proper coefficients from decimal numbering system, to parallel add the multiplied digits with the proper coefficients, to create the number from entered digits at electronics environment (in a 32 bits register)
