Just learn how to CODE a computer: The very basic principles of any computer. Most people learn how exactly a computer works by buying this App. Learn how to CODE. Tell me how a microprocessor works. Here you can learn it. Please like my App and write a customer review. 4917emu is an hypothetical microprocessor that was used in a computer course named COMP1917 at the UNSW University of New South Wales 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. There is a Extended Instruction Code set. For example the following 4917 machine code program would print the numbers from zero to 15: 8 0 3 11 1 15 0. Happy hacking ;)
LCM GCD Prime Factor Math
