This repository contains the design and implementation of a 4-bit processor capable of executing 4 instructions. This is the basic version of Nano processor: Nano Processor-Version 2
Instruction Set: The processor supports a set of 10 instructions designed for basic computing tasks.
| Instruction | Description |
|---|---|
MOVI |
Move immediate value to register. |
ADD |
Addition operation. |
NEG |
Negate operation. |
JZR |
Jump if zero instruction. |
- Simulation: The processor design can be simulated using a hardware description language (VHDL) simulator such as Vivado
- Synthesis: Synthesize the processor design for specific FPGA platforms using synthesis tools like Vivado
- Programming: Write programs in assembly language using the supported instruction set, assemble them, and load them onto the ROM for execution.
