SCPU

Introduction

SCPU is a simple 8-bit CPU which is inspired by RISC and CISC Architectures and designs

Implementation of SCPU is done in verilog and tested on FPGA

• Here is the ppt for mid report of project ppt

Features

• 8-bit data bus
• 16-bit address bus (64kb RAM space)
• 8 8-bit general purpose registers (r0 to r7)
• separate buses for data and address
  • so pair of consecutive registers can used as pointers
• many instructions can directly work on data from memory unlike in RISC machines
• memory mapped IO
• tools such as assembler are provided

Instructions

opcodes can be found in google sheets inst

Architecture

Examples

finding nth fibonacci number

Future Goals

• implement stack and remaining ALU operations
• Emulator for testing without hardware
• More test cases
• adding more hardware features
  • UART boot loader
  • interrupts

Contribution

I am open for ideas, discussions and any kind of contribution

About Me

I started learning about how CPU works and how to use an FPGA to implement the hardware. lot more to learn and really excited about it
