I'm back again.

After another long hiatus, and moving back from Norway, I've started work again.

Today I got all of the other ALU instructions working, and put in a first pass at the shifter logic. I've found one bug in it so far, and I don't think I'm going to get through it tonight.

  • addci
  • add
  • addi
  • subc
  • subci
  • sub
  • subi
  • or
  • ori
  • xor
  • xori
  • and
  • andi

To Go:

  • lbr
  • lba
  • lsbr
  • lsba
  • sbr
  • sba
  • ssbr
