Abacus is a typical RISC architecture; the following data type specifies however only the scalar part of the instructions, while there are also vector instructions. See also Abacus reference card. For addition, subtraction, multiplication, division there are four variants:

AbcOp(rd,r1,r2) means signed operation Reg[rd] := Reg[r1] op Reg[r2]
AbcOpU(rd,r1,r2) means unsigned operation Reg[rd] := Reg[r1] op Reg[r2]
AbcOpI(rd,r1,c) means signed operation Reg[rd] := Reg[r1] op c
AbcOpIU(rd,r1,c) means unsigned operation Reg[rd] := Reg[r1] op c

The following are logic operations

AbcAnd(rd,r1,r2) means bitwise Reg[rd] := Reg[r1] & Reg[r2]
AbcOr(rd,r1,r2) means bitwise Reg[rd] := Reg[r1] | Reg[r2]
AbcXor(rd,r1,r2) means bitwise Reg[rd] := Reg[r1] ^ Reg[r2]
AbcNeg(rd,r1) means bitwise Reg[rd] := !Reg[r1]
AbcShift(rd,r1,r2) means left shift of Reg[r1] by Reg[r2] bits to Reg[rd]

The following are comparison operations

AbcSlt(rd,r1,r2) means signed operation Reg[rd] := Reg[r1] < Reg[r2]
AbcSltU(rd,r1,r2) means unsigned operation Reg[rd] := Reg[r1] < Reg[r2]
AbcSlet(rd,r1,r2) means signed operation Reg[rd] := Reg[r1] <= Reg[r2]
AbcSletU(rd,r1,r2) means unsigned operation Reg[rd] := Reg[r1] <= Reg[r2]
AbcSeq(rd,r1,r2) means equality Reg[rd] := Reg[r1] == Reg[r2]
AbcSne(rd,r1,r2) means negated equality Reg[rd] := Reg[r1] != Reg[r2]

The following are memory operations

AbcMove(rd,c) means Reg[rd] := bv2int(c)
AbcOvf(rd) means Reg[rd] := ovflw
AbcLoad(rd,r1,r2) means Reg[rd] := Mem[Reg[r1] + Reg[r2]]
AbcLoadI(rd,r1,c) means Reg[rd] := Mem[Reg[r1] + bv2nat(c)]
AbcStore(rd,r1,r2) means Mem[Reg[r1] + Reg[r2]] := Reg[rd]
AbcStoreI(rd,r1,c) means Mem[Reg[r1] + bv2nat(c)] := Reg[rd]

The following are control flow operations

AbcBez(rd,c) means if(Reg[rd]==0) pc := pc + bv2int(c)
AbcBnz(rd,c) means if(Reg[rd]!=0) pc := pc + bv2int(c)
AbcJmp(rd) means pc := pc + Reg[rd]

The following are operations for thread control where additionally a load-link register is modified and checked:

AbcLdLink(rd,r1,c) means Reg[rd] := Mem[Reg[r1] + bv2nat(c)]
AbcStCond(rd,r1,r2) means Mem[Reg[r1] + Reg[r2]] := Reg[rd]
AbcSync waits until the store buffer is emptied
