In depth
A closer look at DIY calculator
The DIY Calculator is based on a very simple microcomputer system comprising a central processing unit (CPU), some memory, and some input and output (I/O) ports (these ports allow the system to “talk” with the outside world). The CPU itself is very straightforward and easy to understand: it has an 8-bit data bus and a 16-bit address bus; it contains a small number of simple registers like an accumulator, index register, and stack pointer; and it supports a very simple instruction set along the lines of ADD, SUBTRACT, SHIFT, ROTATE, AND, and OR. The application also provides a virtual calculator front panel with buttons, lights, and a pseudo-liquid crystal display (LCD).
