Learn Microprocessor Basics with 4917emu (iOS)

Back in college my lecturers used something called a “Little Man Computer” (LMC), which was simplified concept of a modern computer, in order to teach assembly code. So it was pretty interesting to receive an e-mail in my mailbox last week regarding a brand new app on the App Store called 4917emu by developer Michael Mustun.

4917emu is based on the 4917 microprocessor (a hypothetical designed just for a computer course named COMP1917 at the University of New South Wales) which was used to teach microprocessor basics. It is 4bit, has 16 memory locations and 4 registers: Instruction Pointer (IP), Instruction Store (IS), General Register 0 (R0) and General Register 1 (R1). Each memory location can store a number between 0 and 15, and there are 16 instructions.

I’m always for teaching tools on iOS devices and this might be a great addition to classroom curriculum. Back in the day, all I had were pen and paper to write down the procedures for the LMC. 4917emu is available on the App Store for free for the iPhone, iPod touch and iPad.
