What is a micro-instruction?
microinstruction: An instruction that controls data flow and instruction-execution sequencing in a processor at a more fundamental level than machine instructions. Note: A series of microinstructions is necessary to perform an individual machine instruction.a micro instruction specifies one or more micro oprations for the system.
What is the relationship between instruction and micro-operation?
in computer central processing units, micro-operations (also known as a micro-ops or μops) are detailed low-level instructions used in some designs to implement complex machine instructionsA micro-operation is an elementary CPU operation, performed during one clock pulse.An instruction consists of a sequence of micro-operations.
What is operation code?
an opcode (operation code) is the portion of a machine language instruction that specifies the operation to be performed. Their specification and format are laid out in the instruction set architecture of the processor in question (which may be a general CPU or a more specialized processing unit). Apart from the opcode itself, an instruction normally also has one or more specifiers foroperands (i.e. data) on which the operation should act, although some operations may have implicit operands, or none at all. There are instruction sets with nearly uniform fields for opcode and operand specifiers, as well as others (the x86architecture for instance) with a more complicated, varied length structure.by: HerLoyd
What is a machine that is made up up two or more simple machines is called a double machine or complex machine or multiple machine or triple machine?
They are called compound machines. :)Hope that helps
What is the slogan of the simple machine?
a machine is use in building
Are processors that use pipelining slower because they have to wait for one instruction to complete the machine cycle before fetching the next?
No. Pipeline processors are faster because they do not have to wait to fetch the next instruction, because the next instruction was "pre-fetched" already.
What do Fetch Decode and Execute mean in a microprocessor?
Fetch Decode Execute. This is the cycle that processors will follow. Fetch the Instruction, Decode it into machine code, Execute the commands
What are the four operations of the machine cycle?
comparing, decoding, executing, nd fetching
What is the Difference between machine op and pseudo op?
A pseudo-op is an assembly language instruction that specifies an operation of the assembler i.e about the base register & its contents e.g. USING instruction. On the other hand, a machine-op instruction. That represents a machine instruction to the assembler e.g. BR instruction is a machine-op instruction
What is the difference between instruction cycle and machine cycle?
an instruction cycle may consist of a number of machine cycles.
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.
What Frees processors from having to wait for one instruction to complete the machine cycle before fetching the next?
A: ALL computer have an I/O and have interrupt signals these signal are there to service whatever is requesting a service. A printer request for instance or a USB device the processor will wait until the service is completed unless it is released. lesson to learn the I/O is the pace of speed not the speed of the CPU which usually loaf waiting for interrupts to be finished. Fast I/O buss means a fast computer.
How do you add new machine language instruction to a processor intsruction set?
To add a new machine language instruction to an processor instruction set, you need to replace the microcode of the processor.
What is machine control instruction?
HLT
One instruction in high level language corresponds to one instruction in machine language?
No. Generally, one instruction in a high level language corresponds to many instructions in machine language.
What are the four steps of the machine cycle and describe what occurs at each step?
fetch decode execute and store in that order.... i do not know the description of each stage i need the answer to that myselfmachine cycle is also called instruction cycleCPU performs following steps to execute an instructionFetchDecodeExecuteStoringFetchload instruction from the memory to execute.this operation performed by control unit.Decodedetermine what the instruction is telling the computer to do,and what operation should be taken.Executeafter decoding and getting the required result,CPU finally execute instruction by ALU(arthematic logic unit).Storingthe process of writing the result to memory is called storing or the process of storing the generated result to the main memory.
What is difference between coherent machine and incoherent machine?
The main difference between coherent and incoherent machine is the consistency in performance. A coherent machine has processors that work in a consistent manner.Ê
