What is Reduced Instruction Set Computer architecture?
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.
What is reduced in both RISC and CISC architecture?
The CISC approach attempts to minimize the number of instructions per program, sacrificing the number of cycles per instruction. RISC does the opposite, reducing the cycles per instruction at the cost of the number of instructions per program.
Why is RISC called reduced?
The focus on “reduced instructions” led to the resulting machine being called a “reduced instruction set computer” (RISC). The goal was to make instructions so simple that they could easily be pipelined, in order to achieve a single clock throughput at high frequencies.
Why is an instruction set needed?
The instruction set, also called ISA (instruction set architecture), is part of a computer that pertains to programming, which is more or less machine language. The instruction set provides commands to the processor, to tell it what it needs to do.
What is the need for reduced instruction chip?
The goal is to offset the need to process more instructions by increasing the speed of each instruction, in particular by implementing an instruction pipeline, which may be simpler given simpler instructions.
What is the best description of Reduced Instruction Set Computer RISC?
RISC, in full Reduced Instruction Set Computer, information processing using any of a family of microprocessors that are designed to execute computing tasks with the simplest instructions in the shortest amount of time possible. RISC is the opposite of CISC (Complex Instruction Set Computer).
What is the best description of reduced instruction set computing RISC?
A processor architecture that shifts the analytical process of a computational task from the execution or runtime to the preparation or compile time. By using less hardware or logic, the system can operate at higher speeds.
What are types of instructions instruction sets exist in computer architecture?
Following are the instruction set architectures:
- Reduced Instruction Set Computer (RISC)
- Complex Instruction Set Computer (CISC)
- Minimal instruction set computers (MISC)
- Very long instruction word (VLIW)
- Explicitly parallel instruction computing (EPIC)
- One instruction set computer (OISC)
What is the meaning of IOP in computer?
An input-output processor (IOP) is a processor with direct memory access capability. In this, the computer system is divided into a memory unit and number of processors. Each IOP controls and manage the input-output tasks. The IOP is similar to CPU except that it handles only the details of I/O processing.
What is a reduced instruction set computer?
A reduced instruction set computer (RISC) is a computer that uses a central processing unit (CPU) that implements the processor design principle of simplified instructions.
How to prepare for a computer architecture interview?
Put forward an example where you performed exceptionally well. Give them a picture of the kind of employee that they are looking for. These are some of the most popular Computer Architecture interview questions. Being prepared with the frequently asked questions will increase your chances of clearing the interview.
What is the instruction set of a computer?
The instruction set of the computer defines the interface between software modules and the underlying hardware; the instructions define what the hardware will do under certain circumstances. Instructions can have a variety of characteristics, including:
What is the implementation of computer architecture?
The implementation, functionality, and organization of any system of computer are explained in detail with many sets of rules and methods. As it is done through the key implementation of Computer Architecture, it is considered as one of the main subjects that students have to grasp in computer engineering.
