Sidenote: Designed to accomodate the syntax of the P3 processor's assembly language, this theme is in no way a finished product. Feel free to contribute to the project or submit an issue detailing a problem with the project or what have you.
Still on a tangent, a color theme is not supplied with this package. It is purely a syntax for the P3 assembly language.
The P3 is a 16-bit word architecture processor used at Lisbon University's Superior Technical Institute (Instituto Superior Técnico da Universidade de Lisboa, IST@UL) in the Introduction to Computer Architecture subject of the Computer Science and Engineering BSc degree.
In practice, during the course's subject, a project is tailored for the first year's first semester students (freshmen, hopefully). Usually, or at least thus far, the project consists of creating a well-known game (or should I say recreating) using the P3 processor simulator, a Java application capable of simulating the assembled code to be loaded onto the processor itself on a later stage, during a demo or for testing purposes, since the simulator's.. not very feasible or reliable, if I may.
A few of the processor's specifications are listed below.
1. Registers
R0 - R7- General use registers (R0holds the constant0)PC- The program counterSP- The stack pointerRE- State register with 5 state bits, EZCNO, whereE: Enable interruptsZ: ZeroC: CarryN: NegativeO: Overflow
2. Memory
- Address space: 64K words
- Word size: 16 bits
3. I/O
- I/O Addresses: Memory Mapped I/O from
