Out of the following which is not a CISC machine. Explanation: None. Explanation: The RISC machine architecture was the first to implement pipe-lining. Explanation: In CISC architecture more emphasis is given on the instruction set and the instructions take over a cycle to complete.
What is not a CISC processor?
Explanation: The semantic gap is the gap between the high level language and the low level language. Out of the following which is not a CISC machine. Explanation: The RISC machine architecture was the first to implement pipe-lining.
What are CISC machines?
A complex instruction set computer (CISC /ˈsɪsk/) is a computer in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions.
Which of the following is an example of CISC processor?
Examples of CISC processors are the System/360, VAX, PDP-11, Motorola 68000 family, AMD, and Intel x86 CPUs.
What is CISC RISC example?
RISC has more transistors on memory registers. CISC has transistors to store complex instructions. ... Example of RISC: ARM, PA-RISC, Power Architecture, Alpha, AVR, ARC and the SPARC. Examples of CISC: VAX, Motorola 68000 family, System/360, AMD and the Intel x86 CPUs.
Which is not a CISC machine?
What is a RISC machine?
A Reduced Instruction Set Computer is a type of microprocessor architecture that utilizes a small, highly-optimized set of instructions rather than the highly-specialized set of instructions typically found in other architectures.
Which of the following is not true about RISC processors?
Which of the following is not true about RISC processors? Explanation: Unlike the CISC, in RISC architecture, instruction microcoding is not required. Explanation: In RISC, each instruction is of the same length, so that it may be fetched in a single operation.
What are CISC and RISC processors?
RISC stands for 'Reduced Instruction Set Computer Whereas, CISC stands for Complex Instruction Set Computer. The RISC processors have a smaller set of instructions with few addressing nodes. The CISC processors have a larger set of instructions with many addressing nodes. Execution time is very less in RISC.
Which of the following is not the part of microprocessor unit?
Answer: register is not the part of microprocessors unit..
Is Intel p6 CISC processor?
The core of the chip is very RISC-like, whereas the external instruction interface is classic Intel CISC. By breaking down the CISC instructions into several RISC instructions and running them down parallel execution pipelines, the overall performance is increased.
Which is CISC processor?
CISC processor have instructions that occupy more than one memory word. A single instruction has several low-level instructions. Each instruction requires more than one clock cycle. CISC instructions have complex addressing modes, complex instructions; hence decoding of instruction is also complex.
Where are CISC processors used?
CISC is most often used in automation devices whereas RISC is used in video and image processing applications. When microprocessors and microcontroller were first being introduced, they were mostly CISC. This was largely because of the lack of software support present for RISC development.
Which of the following is 4 bit architecture?
4. Which of the following is a 4-bit architecture? Explanation: National COP series is a 4-bit processor whereas MC6800 is an 8-bit processor, 8086 is a 16-bit processor and 80386 is a 32-bit processor. 5.
Which of the following is a CISC architecture?
MC68020 is having a CISC architecture. CISC architecture is used for code efficiency whereas RISC architecture is used for speeding up the processor. ARC, Atmel AVR, and Blackfin are RISC architectures.
Which of the following is not a example of system software?
Which of the following is not an example of system software? Explanation: A system software is responsible for controlling the operations of a computer system. Word Processor is an application software since it is specific to its purpose.
Which of the following is an example of RISC processor?
Examples of processors with the RISC architecture include MIPS, PowerPC, Atmel's AVR, the Microchip PIC processors, Arm processors, RISC-V, and all modern microprocessors have at least some elements of RISC.
Which of the following is not a microprocessor brand?
Dell is the answer.
Which of the following is not the part of control unit?
Explanation: Input Unit helps computer to take input from the user. So it is not a part of CPU.
Which of the following is not a function of an operating system?
3. Therefore ,Virus Protection is not the function of OS.It is function of Firewall and Antivirus.
What is RISC and CISC Tutorialspoint?
RISC: Reduce the cycles per instruction at the cost of the number of instructions per program. CISC: The CISC approach attempts to minimize the number of instructions per program but at the cost of increase in number of cycles per instruction.
Is ARM processor RISC or CISC?
An ARM processor is one of a family of CPUs based on the RISC (reduced instruction set computer) architecture developed by Advanced RISC Machines (ARM). ARM makes 32-bit and 64-bit RISC multi-core processors.
Which of the following is not a visible register?
5. Which of the following is not a visible register? Explanation: MAR or the memory address register is not a visible register. This register is user inaccessible.
Which one of the following is a characteristic of CISC processor?
Characteristic of CISC –
Complex instruction, hence complex instruction decoding. Instructions are larger than one-word size. Instruction may take more than a single clock cycle to get executed. Less number of general-purpose registers as operation get performed in memory itself.
