this is my EE homework. I thought it looked
poetic.

mov[cx], dx

Address line points to cx
Data line reads cx
Address line points to a cell in RAM
Data line writes contents of cx into that cell.

Address line points to dx
Data line reads dx
Address line points to a cell in RAM
Data line writes contents of dx into that cell.

Address line points to command
Data line reads command
Address line points to a cell in RAM
Data line writes contents of command into that
cell.

Address line points to cell of command
Data line reads command
[
Address line points to dx cell
Data line reads contents of dx cell
Address line points to cx cell
Data line writes contents of dx cell into cx cell
]

ax=ax+bx

CPU address line points to ax
CPU data line reads ax
CPU address line points to a cell in RAM
CPU data line writes contents of ax into RAM

CPU address line points to bx
CPU data line reads bx
CPU address line points to a cell in RAM
CPU data line writes contents of bx into RAM.

CPU address line points to operand
CPU data line reads operand
CPU address line points to a cell in RAM
CPU data line writes contents of operand into RAM

CPU address line points to ax, data line fetches &
stores into ALU
CPU address line points to bx, data line fetches &
stores into ALU
CPU address line points to operand, data line
fetches &stores to ALU
ALU executes operand upon the variables ax and bx.

CPU address line points to cell with ax
CPU data line writes ALU solution into RAM
