What are the four distinct actions that a machine instruction can specify?
• The processor fetches the instruction from memory • Program counter (PC) holds address of the instruction to be fetched next • PC is incremented after each fetch • Fetched instruction loaded into instruction register
IS OPCODE FETCH MACHINE CYCLE ENOUGH FOR THE INTRUCTION MOV MA IN 8085 TIMING DIAGRAM?
In the 8085 microprocessor, the opcode fetch machine cycle is not sufficient on its own for executing the MOV MA instruction. While the opcode fetch cycle is responsible for retrieving the instruction from memory, additional machine cycles are required to perform the data transfer or execution of the instruction. Specifically, the MOV MA instruction involves both an opcode fetch cycle and a memory access cycle to complete the operation. Therefore, multiple machine cycles are necessary for executing this instruction effectively.
What is called the collection of commands that a specific CPU executes?
machine code instruction set or assembly language
What is a pedestal drilling machine?
pedestal drilling machine is a machine.... which is used for drilling metals and other elements... it is used in industries to make machine holds etc..
How are instructions given to a computer?
An extremely simple thing called machine code. Im not insulting you with the extremely simple thing, that just means its easy for the computer to follow. Machine code tells the computer what to do and when to do it.
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 types of operands are typical in machine instruction sets?
Addresses, Numbers, Characters, Logical Data (source: Computer Organization and Architecture, William Stallings)
Does wells' the time machine have picaresque elements?
"The Time Machine" by H.G. Wells does not contain typical picaresque elements such as a rogue or a humorous journey. Instead, it focuses on themes of time travel, social criticism, and scientific invention.
What is the difference between instruction cycle and machine cycle?
an instruction cycle may consist of a number of machine cycles.
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 elements of instruction?
these essential elements are 1,operation code (op code) and 2.address field both compose the computer instruction
How to calculate the number of machine cycle and opcode fetch of any instruction?
To calculate the number of machine cycles and opcode fetches for any instruction, you need to refer to the architecture's documentation, which outlines the instruction set and the corresponding cycles for each instruction. Typically, an opcode fetch counts as one machine cycle, and the total machine cycles for an instruction will depend on its complexity and any additional operations it requires, such as data fetches or memory accesses. Analyze the instruction's microarchitecture to determine the number of cycles needed for its execution, including any potential delays or dependencies.
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.
Is a microoperation the same thing as a machine instruction?
No, a microoperation is not the same as a machine instruction. A machine instruction is a higher-level command that tells the CPU to perform a specific operation, such as adding two numbers or moving data. In contrast, a microoperation refers to the basic, low-level operations that occur within the CPU to execute a machine instruction, such as transferring data between registers or performing arithmetic operations at the bit level. Essentially, microoperations are the building blocks that enable machine instructions to be carried out.
What is Typical and non typical transition element?
group IIB elements (Zn Cd,Hg) don't have partially filled d-subshell either in elements or in their ionic ionic state, and neither they show typical properties of transition elements.... Elements of group IIIB are also non typically. From Lion Heart Baloh
