Description of Microprocessor Simulator

An x86 style microprocessor simulator for students of low level programming. The simulator is based on the low eight bits of the 8086 chip. It can be single stepped or continuously run. The CPU registers, and RAM contents are visible and animated. The program includes simulated peripherals including traffic lights, a heater and thermostat and seven segment displays. These can be controlled by writing simple low level programs. Advanced programming techniques can be learned such as handling hardware interrupts, writing procedures and functions and passing parameters via registers, RAM or the stack. The simulator is simple and fun to use with beginners and powerful enough for quite advanced students. It has been designed to help students learn about bits, bytes and data representation. The program has built-in limitations such as an 8 bit address bus. Learners quickly encounter these limitations (which also apply to real life systems) and have to write efficient, compact code to solve their programming problems. About half of all the code in the world is written for tiny embedded systems like TV remote controllers. This simulator provides a straight forward introduction to this style of programming.
