The purpose of the CPU : To perform the fetch-decode-execute cycle to processexecute instructions Describe the stages of fetch execute cycle : Instructions are fetched from memory The control unit will decode the instructions The decoded instruction is then executed so that the CPU performs continuously The process is repeated Describe the role of a register : A high-speed memory units within the CPU. Can only store a single value at a time (8,16,32,64 bits depending upon the architec...

The fetched instruction is loaded into the Program Counter. correct answers FALSE Interrupts are provided primarily as a way to improve processor utilization. correct answers TRUE An example of a multicore system is the Intel Core i7. correct answers TRUE It is not possible for a communications interrupt to occur while a printer interrrupt is being processed. correct answers FALSE The interrupt can occur at any time and therefore at any point in theexecution of a user program. correc...
