What is a 80x86 instruction set?
The leainstruction takes the form: The 80x86 Instruction Set Page 249 lea dest, source The speciﬁc forms on the 80x86 are lea reg16, mem lea reg32, mem (3) (3) Available only on 80386 and later processors. It loads the speciﬁed 16 or 32 bit general purpose register with the effective addressof the speciﬁed memory location.
What is extended division using 8086 instructions?
; Extended division using 8086 instructions. ; ; Like multiplication, there are separate instructions for signed ; and unsigned operands. ; ; It is absolutely imperative that these instruction sequences sign ; extend or zero extend their operands to 32 bits before dividing. ; Failure to do so will may produce a divide error and crash the ; program.
What opcode byte does 8086 use?
Instructions like add, adc, sub, sbb, and many others in the 8086 instruction set use a mod-reg-r/m byte to support two operands. Unfortunately, there aren’t enough bits in the 8086’s opcode byte to support all instructions, so the 8086 uses the reg bits in the mod-reg-r/m byte as an opcode extension. For example, inc, dec, and
