True or False: Zero address instructions specify their operands explicitly.
Consider how operands are handled in stack operations.
Design a simplified opcode table for a fictional CPU with 5 different operations. Each should have a unique 3-bit opcode.
Keep it under 8 to fit in 3 bits.
Discuss the trade-offs between using three address instructions vs. zero address instructions in CPU design.
Think about how each approach manages memory and processing power.
