Universal Machine

The Universal Machine is a Virtual Machine presented at the Ninth annual ICFP Programming Contest. The VM is capable of running the UMIX operating system, which was written for the purpose of the competition.

The VM contains the following features:

• 32-bit architecture
• 14 instructions
• 8 general-purpose registers
• a heap that maps distinct 32-bit values to allocated arrays
• array allocation, deallocation and update
• character-based input and output
• a simple control flow
• math and logic instructions

Hierarchy

• src - contains vm.c which is the source file
• test_files - contains codex.umz and sandmark.umz that can be used as input files
• Universal-Machine-Report.pdf - the report file

Run

• make - creates [vm] which takes the name of a file as the first argument
• make sandmark - compiles the vm and executes the sandmark.umz file
• make codex - compiles the vm and executes the codex.umz file, needs the decryption key: (\b.bb)(\v.vv)06FHPVboundvarHRAk
• make clean - removes the [vm] executable
