public class Processor01
extends Object
implements CalcCPU, CalcConstants
This class is an equivalent of a microprocessor in a calculator (minus the display logic). It executes commands and is capable of sending messages to a display unit (panel). Logic organization:
2 number registers (double): R1, R2, 1 memory register (double): RM. This class can be further broken down into:
a Command Control Unit (CCU),
an Arithmetic and Logic Unit (ALU) and
Registers

The source code.
