SimProc is awesome, mainly because it doesn't exist at all.
SimProc means Simple Processor or Simulated Processor. As you wish. SimProc is a 8-bits CPU that only exists on the paper. It was never manufactured. Nor even designed. There are no schematic docs. It has been fully conceived to create virtual systems that won't ever see the light of the day. SimProc is only a set of documented CPU instructions, with their binary coding & execution timing specifications. That's all.
On this repository, you will find emulator & dev tools to write and execute software for SimProc.
Fun.
Did you ever dream to design your own 8-bits microcomputer? I did. Many times. This is one step forward.
It also allows me to learn one of the most interesting programming languages we have in sight: Rust.
Go to Rust website, download and install the latest Rust distribution. Then, from your working copy execute:
cargo build --release
This will download all dependencies and build the binaries in target/release
subdirectory.
SimProc may be used as a library to build your own virtual computer machine. It
also provides some tools useful to develop and debug SP-80 code. You will find
them in the target/release directory after a successful build.

spasmis the SimProc assembler. You can use it to assemble your source code into binary machine code. Executespasm --helpto know how to use it. -
spmis the SimProc Machine. It is a very simple machine with SP-80 CPU that maps stdin and stdout to the IO port 0x10. In other words, you can write SP-80 code that reads and writes from and to your terminal usinginandoutinstructions.
