Another CPU Project from me. An 8-Bit CPU called RC8001.


Current features:

• 14 Function ALU

  -add
  -sub
  -inc
  -dec
  -cmp
  -not
  -xor
  -xnor
  -and
  -nand
  -or
  -nor
  -shl
  -shr

• 4 Bit ALU Flags register:

   -Carry
   -Zero
   -Sign
   -Negate

• 4 General Purpose Registers (dual-read)

  -Accumulator( Always the result of the ALU)
  -bx (data Register)
  -cx (data Register)
  -dx (data Register)

• 32 Bytes of RAM in 32 Adresses with Adresspointer

• Stackpointer LIFO-principle

• 8 Bit Adressregister for I/O (Up to 256 I/O-Device possible)

• Call and Interrupt capability

• 2 Programs each 32 lines programmable Program-Memory with Jumpable Programcounter

• Statusflags:

  -Overflow: If the Input Number exceeds the 8 Bit Number
  -Reset: CPU is in Reset State
  -HLT: CPU is in Halted State
  -INT: CPU is in an Interrupt State
  -WAIT: CPU Waits for an User Input or Ready Signal from I/O-Device
  -ERROR: If the CPU is in an Error State, automatically halts the CPU


If you want to see me Building the CPU, I make a Timelapse about that CPU on my YouTube channel: https://www.youtube.com/playlist?list=PL2RlK0q2FriklcTnPk6qrdz60aGrD5pW5
