Question

Given the above image, explain where each of these stated operands is stored or located and how we would reference them in an instruction. 

Operand used as a source (item used in the operation)
• A signed constant in the instruction
• An unsigned constant in the instruction
• The contents of a general-purpose register
• The contents of a memory location
Operand used as a destination (location to hold the result)
• A general-purpose register
• A contiguous pair of general-purpose registers
• A memory location
Figure 7.2 Examples of items an operand can reference in a 3-address pro-
cessor. A source operand specifies a value and a destination
operand specifies a location.
