A central processing unit (CPU) performs the fetch-decode-execute (FDE) cycle. (a) Give the name of two registers that are used in the fetch stage of the cycle. 1 \_\_\_\_ 2 \_\_\_\_ [2] (b) Describe what happens at the decode stage of the cycle. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ [3] (c) Give one register in the CPU that is used in the execute stage of the cycle. \_\_\_\_ [1] (d)Buses are used in the CPU to transmit data through the FDE cycle. Circle three buses that are used in the CPU. | fetch | address | register | execute | | :--- | :--- | :--- | :--- | | data | decode | calculation | | | central | value | binary | control | [3] (e) A user changes their CPU from one with a dual core and a clock speed of 2.4 GHz to one with a dual core and a clock speed of 3.5 GHz.
