1The Fetch-Execute Cycle
The [blank_start]PC[blank_end] register holds the address of the next [blank_start]instruction[blank_end]. This value is passed to the [blank_start]MAR[blank_end]. The instruction in memory at this address is then retrieved and placed in the [blank_start]MBR[blank_end]. At the same time the PC increments by 1. The instruction is then passed to the [blank_start]CIR[blank_end] where it is [blank_start]decoded[blank_end] and [blank_start]executed[blank_end]. Any results of calculations are placed in general purpose registers. Results of comparisons, interrupts and notification of overflow are placed in the [blank_start]status[blank_end] register. The process repeats.- APC
