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
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..
What is called the collection of commands that a specific CPU executes?
machine code instruction set or assembly language
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 instruction buffer register?
It is employed to hold temporarily the right hand instruction from a word in memory.. For example, The IAS machine's basic unit of information was a 40-bit, so that two instructions could be stored in each 40-bit memory location. Each instruction consisted of an 8-bit {operation code} and a 12-bit address. Hence the IBR (Instruction Buffer Register) is used to temporarily hold Right hand instruction for the next use.
What types of operands are typical in machine instruction sets?
Addresses, Numbers, Characters, Logical Data (source: Computer Organization and Architecture, William Stallings)
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
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
What elements do an integrated circuit contain?
The main elements present in typical IC chips are:siliconoxygenaluminumboronnitrogenphosphorusindiumarsenicThe main elements present in typical IC lead frames/pins etc. are: copperaluminumtingoldThe main elements present in typical IC plastic packages are: carbonhydrogenoxygenphosphorussulfur
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 an instruction phase together with the execution phase called?
The instruction phase together with the execution phase is called a "Machine Cycle".
What is the Language programmer writes one mnemonic instruction for each machine level instruction?
It is an assembler language programmer
