e1-268H

Implementation of Notch's dcpu-16 CPU in Haskell.

Status

• Basic infrastructure of the emulator
• Command line interface
• Test suite
• Assembler
• Debugger interface (tui, breakpoints, inspect/change memory and registers, disassemble, etc)
• Peripherals (video, keyboard, serial interface, etc)
• Cycle accurate simulation?

Building

stack build

Running

There's no user interface yet, so fire up GHCi...

stack repl

...and load the example:

ghci> import qualified Data.ByteString as B
ghci> import Control.Monad.Trans
ghci> import Control.Monad

ghci> readProgram = lift . B.readFile $ "examples/32-bit-add.hex"

ghci> runIOComputer (readProgram >>= loadProgram >> replicateM_ 5 execInstruction >> dumpMachine >>= lift . putStr) newIOComputer
