Respuesta :
When the CPU performs the work described in the commands, this stage is known as execute.
The CPU works on the tasks outlined in the program commands during the execute phase. Addition, subtraction, multiplication, division, and other mathematical and logical operations are carried out by specialized hardware on the CPU.
The relevant functional units of the CPU receive the decoded information from the control unit of the CPU as a series of control signals to carry out the instructions, such as reading values from registers, sending them to the ALU for mathematical or logical operations, and writing the results back to a register.
The ALU sends a condition signal back to the CU if it is involved. The operation's output is either transmitted to an output device or kept in the main memory. The PC may be updated to a different location from which the subsequent instruction will be fetched depending on the feedback from the ALU.
