what is the two subunits of a cpu
The CPU itself is comprised of several subunits, each playing a specific role in the processor's overall operation. These subunits are the Arithmetic Logic Unit (ALU), the registers, and the Control Unit.1  The Arithmetic Logic Unit (ALU) is the collection of circuitry that performs actual operations on data.s was discussed in Chapter 1, virtually all modern computers have the same basic layout, known as the von Neumann architecture. This layout divides the hardware of a computer into three main components: memory, Central Processing Unit (CPU), and input/output devices.
