We have three CPU's, which all use the same instruction format.
- Processor A supports an add instruction.
- Processors B and C support both add and multiply instructions.
- Processor B has a 4-bit multiplier in the ALU.
- Processor C has an 8-bit multiplication unit in the ALU.
- All processors are accumulator-based and support load and store operations.
- Processors A
and B are microprocessors manufactured using a 180nm process.
- Processor C was assembled
from discrete components.
