Virtual machine in python.

I'd like to build a simple virtual machine/CPU simulator in python. with specific instructions. If you worked on similar projects before and used to python and assembly languages contact me for more detail basically creating python app that will have the following 4 files: 1. A CPU which includes all the 32-bit registers and the Program Counter PC. 2. A memory that can load the software (code and data) from a file. 3. A memory-mapped IO subsystem, such as UART to print out messages on screen. 4. A Virtual Bus (VB) to redirect read and write operations to the correct component. memory-mapped components including the main memory must expose read and write functions to allow the CPU to read from and write to them. The CPU reset address is 0x00. The PC will be incremented by 4 after each instruction except when executing a branch or jump instruction. You need to structure your VM in a way aligned with the course contents. For instance, the CPU needs to fetch the instruction from the memory using its read operation and then decode the instruction and read all required operands. After that, the CPU needs to execute the instruction and finally update its registers, such as the destination register and the PC. Once you finish a cycle of execution, you start the next cycle by fetching the next instruction based on the new value of the PC.
