The decode stage uses other programs or compilers either built into the processor, OS (operating system) or third party software. The compiler runs through a language like C or VB and converts the code into one the CPU understands (binary)

What cycle is used by the CPU to execute instructions in a programs?
fetch,decode
What is a CPU cycle?
The sequence of steps that a CPU performs.Also known as fetch-decode-execute cycle.
What is memory cycle in CPU?
fetch decode exec store
Explain steps involve in instruction execution cycle?
The two-phase process for executing instructions on a typical CPU involves a fetch step and an execute step. Fetch is where the instruction is loaded from memory and execute is where the actions detailed in the instruction are carried out.
What is a cycling machine?
Each time the CPU executes an instruction, it takes a series of steps. The complete series of steps is called a machine cycle. A machine cycle can be divided into two smaller cycles. These are instruction cycle and execution cycle. Instruction cycle: In instruction cycle CPU takes two steps-- 1. Fetching: Before the CPU can execute an instruction, the control unit must retrieve or fetch a command or data from the computer's memory. 2. Decoding: Before a command can be executed, the control unit must decode the command into instruction set. Execution cycle: In execution cycle CPU also takes two steps-- 1. Executing: When the command is executed, the CPU carried out the instructions in order by converting them into macrocode. 2. Storing: The CPU may be required to store the result of an instruction in memory.
Is the CPU updating cycle another name for the CPU processing cycle?
true
What is CPU cycle time?
The CPU cycle time is the time between start up and shutdown
Which CPU's can decode HD video, like h.264 in real-time?
There is the New all-in-one VIA chipset can decode 1080p video in real time.
CPU does not distinguish data and operation code explain?
As far as the bus interface is concerned, there is no real difference between data and instructions. Except for the S0 pin, an opcode fetch will look the same as a memory read. There is one extra clock cycle following an opcode fetch, which is used by the CPU to decode and process the opcode, but the bus does not care because there is no sequence initiation with ALE.
In what all situations DMA is used?
DMA (Direct Memory Access) can be used during the CPU's "busy time", such as when the CPU is processing a read/write cycle, the DMA will take over to perform other tasks while the CPU is busy.
Is the machine cycle same as the CPU?
yes
How does DMA module communicate with CPU?
DMA can communicate with CPU using Cycle stelaing process
