I finished making my nova core v1 but forogot to wire any devlogs so here is my readme i hope it is ok….. Nova Core is a custom 16-bit CPU designed and built from scratch in Verilog.

Demo https://zoomwag.github.io/nova-core/

The project is focused on learning how processors work by designing each major component individually and combining them into a complete CPU.

Here are some images of the cpu

Features

• 16-bit CPU architecture
• Custom instruction set
• Custom ALU
• Accumulator-based design
• Program counter
• Instruction register and decoder
• Control unit
• ROM and RAM
• Status flags
• Written entirely in Verilog

NovaCore CPU Instruction Set

Instruction format

Every NovaCore instruction is 16 bits wide:

Bit:  15              12 11                              0
      ┌─────────────────┬─────────────────────────────────┐
      │  4-bit opcode   │         12-bit operand          │
      └─────────────────┴─────────────────────────────────┘

• The opcode tells the CPU what operation to perform.
• The operand can contain a constant, RAM address, or program address.
• Some instructions do not use the operand

finshed

did a bunch if solering and cad it look srly good

cONVERETED IT INTO AN UNDERCUTTER

did a bnch if stuff soldered some stuff together and stareted learning hos to code this will be fun

I started doing cad and did a bunch of research

A LOT HAPPNED. so basiclally after finishing my pcb (which i forogot to record becuase for some reasont he non laspe screenshot thing didnt work) i found it cost 150 dollars which insane. becusae iof this i deceded to just ork around a 30 dollar all in one board

I finished making all the charging and battery volatage schematics and started on the esp32

I did a lot of research and made the usbc interface
