Decode-Fetch-Execute
|
Detailed explanation-1: -The CPU works by following a process known as ‘fetch, decode and execute’. The CPU fetches an instruction from memory, decodes this instruction and then executes it. The CPU carries out this cycle continuously, millions of times per second.
Detailed explanation-2: -The basic operation of the Central Processor Unit utilises what is called the ‘fetch-decode-execute’ cycle. The CPU is designed to load, read and execute a set of instructions – the CPU instruction set. It fetches the instructions from the main memory, decodes them, and executes them.
Detailed explanation-3: -The Fetch Execute Cycle In the Advanced Higher course, the fetch-execute cycle builds on the information from Higher and includes the role of three internal processor registers: Memory Address Register (MAR) Memory Data Register (MDR) Instruction Register (IR)
Detailed explanation-4: -There are four steps that nearly all CPUs use in their operation: fetch, decode, execute, and writeback.
Detailed explanation-5: -Fetch is the retrieval of data by a software program, script, or hardware device. After being retrieved, the data is moved to an alternate location or displayed on a screen. Fedtch-decode cycle, Hardware terms, Read, Software terms.
