LMC, The Little Man Computer

The imagination of a little creature operating the computer by itself...

The Little Man Computer (LMC) is an instructional model of a computer. The LMC is generally used to teach students, because it models a simple von Neumann architecture computer - which has all of the basic features of a modern computer.This instructional model was created by Dr. Stuart Madnick in 1965.

To execute a program, the little man performs these steps:
@ check the Program Counter for the mailbox number that contains a program instruction
@ fetch the instruction from the mailbox with that number
@ Increment the Program Counter (so that it contains the mailbox number of the next instruction)
@ decode the instruction (includes finding the mailbox number for the data it will work on)
@ fetch the data from the mailbox with the number found in the previous step
@ execute the instruction
@ store the new data in the mailbox from which the old data was retrieved
@ Repeat the cycle or halt
