Operands That Combine Multiple Values Sofar we have interpreted operand value as a number that denotes either a constant, register,ormemory Combining operand values to obtain true value

e pipeline operand registers into register files. Explicit operand forwarding lets software opportunistically orchestrate the routing of operands through the forwarding netwo.

Operand is at a memory address pointed by a register— ST {r1 [M (X)]}, r2; source operand is register r2 and destination operand is a memory address X pointed by the register r1

The simplest design is to have one processor register (called the accumulator) and two fields in the instruction, one for the opcode and one for the operand. Any operation that does not need …

Indexed addressing uses a register (implicitly or explicitly) as an offset, which is added to the address in the operand to determine the effective address of the data.

After accessing the operand, the contents of register are automatically incremented to the next operand in memory. The increment step is 1 for byte-sized operands, 2 for 16-bit operands, …

Same for destination operand, except... How does caller function jump to callee function? How does callee function jump back to the right place in caller function? How does caller function …
