8085 Simulator

8085 Simulator provides developers with a complete toolkit intended for programming an Intel 8085 8-bit microprocessor. The main advantage of this type of programs is that it enables you to practice your skills without having to purchase high-cost hardware and risk damaging it.

The application comes with a simple and an advanced mode, aiming to target both beginner and experienced users. However, regardless of your choice, basic microprocessor programming knowledge is required, as you should know a thing or two regarding the internal architecture of the Intel 8085, its programming model, addressing modes and instruction set.

Selecting the 'Simple' mode reveals a window comprising the instruction field, along with the INT and RES buttons for interrupting or restarting instructions. On the other hand, the 'Advanced' mode enables you to write instructions, control the execution speed, as well as view the memory map, where you can explore the memory locations and edit their values.

The list of instructions is neatly displayed within an organized table, along with their address. You can easily assign labels, enter mnemonic instructions with operands, view the corresponding memory addresses and register values.

The execution speed is adjustable, but the register values cannot be edited. The current configuration can be either executed or saved locally for later use and editing in a file containing the values of registers, the execution speed, the address range and the memory.

While some complex instructions (such as those for intefacing or interrupting programs) might not work correctly on the simulator, 8085 Simulator remains a reliable tool for programming an Intel 8085 microprocessor in a virtual environment. It is operationally similar to the hardware device, which makes it of utmost help to all engineering students who don't have the financial resources to practice on hardware boards.
