Basic architecture & making a program

Von Neumann Architecture

Early computer design.

CPU: ALU, CU with instruction register and program counter

The CN sees memory contents in bits, 1 or 0. That’s called a binary program.

How to make binary program?

• Opt. 1: program bit by bit

• Opt. 2: compile to binary.

  • C++ is a compiled language.

  

• Opt. 3: interpreter that converts & executes a HLL, line-by-line
