- Little Man Computer CPD Pack: Excellent set of resources from a Little Man Computer focused Master Teacher CPD session.- Short video tutorial introducing students to Assembly Language using the Little Man Computer Little Man Cave Sign, Little Boy Decor, Boys Room Sign, Decor for Son, Playroom Sign, Nursery Sign, Boy Present, Playroom Decor.- Original OCR recommended Java Script version of the LMC (Note: this version may now be blocked due to the recent JAVA update).- Enhanced online version of the VB.Net LMC simulator created by Peter Higginson.(Downloadable VB.Net version of the Little Man Computer).The LMC can be programmed using either 'Machine Code' or 'Assembly Language'. The LMC is based on the concept of a little man (shut in a small room or inside a computer) acting like the control unit of a CPU i.e. fetching instructions from memory, decoding and executing the instructions, and managing the input and output.

It is based on the Von Neumann architecture featuring a central processing unit consisting of an arithmetic logic unit and registers, a control unit containing an instruction register and program counter, input and output mechanisms and memory to store both data and instructions. The Little Man Computer (LMC) is a simulator which models the basic features of a modern computer. Understand how instructions are stored and executed within a computer system.Use two or more programming languages, at least one of which is textual, to solve a variety of computational problems.Understand the concept of machine code and assembly language instructions.

Describe the function of the CPU as fetching and executing instructions stored in memory.

You can see the original version by clicking here. Students also explore the Little Man Computer simulation to demonstrate the fetch-execute cycle.Ĭredits: This lesson is based on the sample Scheme of Work supplied by OCR. In this lesson, students look at the CPU in detail, exploring the three major parts: Arithmetic/Logic Unit (ALU), Control Unit (CU) and Memory.
