What does the CPU consist?
A CPU is made up of the control unit (CU), instruction decoding unit and an arithmetic logic unit (ALU).
What does the CPU consists of?
A CPU is made up of the control unit (CU), instruction decoding unit and an arithmetic logic unit (ALU).
What does the CPU consist of and what do the letters CPU stand for?
The letters CPU stand for Central Processing Unit. A CPU is made up of the control unit, instruction decoding unit and an arithmeticlogic unit.
What term refers to the process of translating an instruction into signals the computer can execute?
decoding
Why processor utilisation rate can be improved in a multimicroprocessor system by an instruction queue?
The bus interface unit provides the func- tions related to instruction fetching and queuing, op- erand fetch and store, and address relocation. This unit also provides the basic bus control. The overlap of instruction pre-fetching provided by this unit serves to increase processor performance through improved bus bandwidth utilization. Up to 6 bytes of the instruction stream can be queued while waiting for decoding and execution.
Decoding means interpreting or translating the instruction into strings of binary digits the computer understands?
Yes
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 do you mean by high Code Density for arm processors?
A high code-density microcontroller architecture with changeable instruction formats has a memory for storing compressed instructions each including a group prefix and at least one index. An instruction decompressor is provided for decompressing the compressed instructions to be executed into original instructions. The instruction decompressor includes a plurality of instruction group decoding tables, each being stored with the original instructions of a predetermined type. One instruction group decoding table is selected based on the group prefix of the compressed instruction for searching the corresponding original instruction therein by the index of the compressed instruction.
What fetches and decodes instruction?
control unit
What is instruction execution time In what unit is a computer speed measured?
about instruction execution time
6 Fetching and decoding of any instruction takes three clock cycles How?
Incorrect. Fetching and decoding of any instruction takes a minimum of four clock cycles in the 8085. T1 = ALE and address emission T2 = Read initiation T3 = Read completion T4 = Opcode decode T1, T2, and T3 are repeated for each additional byte of the instruction. In all cases, Twait, if indicated by not READY, is inserted between T2 and T3.
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.
