What does RISC stand for in arm?
Advanced RISC Machine (ARM) is a processor architecture based on a 32-bit reduced instruction set (RISC) computer. Licensed worldwide, the ARM architecture is the most commonly implemented 32-bit instruction set architecture.
What are CISC and RISC?
CISC and RISC (Complex and Reduced Instruction Set Computer, respectively) are dominant processor architecture paradigms. Computers of the two types are differentiated by the nature of the data processing instruction sets interpreted by their central processing units (CPUs).
What does CISC stand for?
Complex Instruction Set Computer
A computer in which individual instructions may perform many operations and take many cycles to execute, in contrast with reduced instruction set computer (RISC).
What is the full form of RISC Mcq?
Explanation: The RISC stands for Reduced Instruction Set Computer.

What is RISC genetics?
Definition. RNA-induced silencing complex, or RISC, is a multiprotein complex that incorporates one strand of a small interfering RNA (siRNA) or micro RNA (miRNA). RISC uses the siRNA or miRNA as a template for recognizing complementary mRNA. When it finds a complementary strand, it activates RNase and cleaves the RNA.
Where are RISC processors used?
RISC is used in high-end applications like video processing, telecommunications, and image processing. CISC is used in low-end applications such as security systems, home automation, etc.
What is the concept of RISC processor?
RISC stands for Reduced Instruction Set Computer. In Reduced Instruction Set Computer (RISC) architecture, the instruction set of the computer is simplified to reduce the execution time. RISC has a small set of instructions, which generally include register-to-register operations.
Why is RISC better than CISC?
Generally speaking, RISC is seen by many as an improvement over CISC. The argument for RISC over CISC is that having a less complicated set of instructions makes designing a CPU easier, cheaper and quicker.
What are the differences between RISC and CISC?
| RISC | CISC |
|---|---|
| Heavy use of RAM | More efficient use of RAM |
What is the main difference between RISC and CISC?
1. RISC is a reduced instruction set. CISC is a complex instruction set.
What is the difference between RISC and CISC processors give an example for each?
The program written for RISC architecture needs to take more space in memory. Program written for CISC architecture tends to take less space in memory. 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.
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.
Is x86 RISC or CISC?
x86 is definitely CISC, but one of the first things a modern x86 CPU does with an instruction stream is convert it into a different instruction set that it uses internally, which is (but doesn’t have to be) more RISC-like. Effectively, they appear as CISC to the outside world, but are RISC under the hood.
What is a CISC architecture?
A complex instruction set computer (CISC /ˈsɪsk/) is a computer architecture 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.
Who coined the term RISC?
One was a project at the University of California, Berkeley, under the direction of David Patterson and Carlo H. Sequin—who coined the term “RISC.” The other project was led by John L. Hennessy at Stanford University.
Which of the following is a RISC architecture?
8. Which of the following is a RISC architecture? Explanation: MIPS possess a RISC architecture whereas 80386, 80286 and Zilog Z80 are CISC architectures.
Which statement is true about RISC?
Explanation: RISC Focus on software is true.
What are the main characteristics of RISC?
Characteristic of RISC –
- Simpler instruction, hence simple instruction decoding.
- Instruction comes undersize of one word.
- Instruction takes a single clock cycle to get executed.
- More general-purpose registers.
- Simple Addressing Modes.
- Fewer Data types.
- A pipeline can be achieved.
What are the motivations behind RISC design?
Simple Addressing Modes
The main motivations are (i) to support complex data structures and (ii) to provide flexibility to access operands. Although this allows flexibility, it also introduces problems. First, it causes variable in- struction execution times, depending on the location of the operands.
