Does a RISC processor have complex instruction sets each requiring several clock cycles for execution?
A pure RISC processor does not, however most modern RISC processors have high speed floating point arithmetic units (and sometimes other functional units) that do take multiple clock cycles for execution. Pipelines and out of order completion mechanisms are used to hide some of the effects of this.

What is a CISC processor?
"CISC" stands for Complex Instruction Set Computer, CISC processor can execute complex instructions in one or more clock cycles. It is meant to differentiate it from a RISC or Reduced Instruction Set Computer, which can only perform one simple instruction in (usually) one clock cycle. A CISC is meant to have many machine level commands carried out as part of a single assembly command. The assembly command is broken into a series of "micro-code" commands which are executed internal to the processor by a "micro-code sequencer".
How does a R.I.S.C processor differ?
The term RISC means Reduced Instruction Set Computer, as opposed to CISC, which is Complex Instruction Set Computer. The RISC processor is different from the CISC process between it has far fewer instructions, but it executes them much faster, because of its simpler internal design.
Please can someone give me the answera) Identify any FOUR 4 drawbacks of a CISC processor compared to a RISC processor?
In CISC, the instruction set is very large that can be used for complex operations while in RISC the instruction set is reduced, and most of these instructions are very primitive. CISC computer's execution time is very high whereas RISC computer's execution time is very less. In, CISC code expansion is not a problem while in RISC code expansion may create a problem. In CISC, decoding of instructions is complex whereas, in RISC, the decoding of instructions is simple. CISC requires external memory for calculations, but RISC requires external memory for calculations. CISC has only a single register set while RISC has multiple register sets are present.
Which one from RISC and CISC is mostly used and why?
RISC (Reduced Instruction Set Computer) architectures are more commonly used in modern computing, particularly in mobile devices and embedded systems, due to their efficiency and performance advantages. RISC designs simplify the instruction set, allowing for faster execution and easier pipelining, which enhances overall processing speed. In contrast, CISC (Complex Instruction Set Computer) architectures, while powerful for certain tasks, often result in more complex hardware and slower execution due to longer instruction cycles. Thus, RISC's focus on simplicity and speed makes it the preferred choice in many applications today.
How do you determine if your processor is RISC or CISC?
RISC (reduced instruction set computer) and CISC (complex instruction set computer) are two major types of processor architecture. These styles differ in the way that they handle incoming instructions, making it difficult to compare the clock speeds of the two types, as a 2.0ghz RISC processor will be faster or slower than a 2.0ghz CISC processor depending on the structure of individual applications. Knowing which type of processor you have is accomplished by knowing which company made your processor.Related Searches:Gaming ProcessorCredit Card ProcessorDifficulty:EasyInstructions1 Open the "Start" menu.2 Press "Run."3 Type in "msinfo32" and press "Enter."4 Click "System Summary" and read the "Processor" tab. If your processor is made by Intel you have a RISC processor. If it was made by AMD you have a CISC processor.
What is the acronym CISC?
Complex Instruction Set Computer.
Which characteristics of RISC systems could be directly implemented in CISC systems?
Certain characteristics of RISC (Reduced Instruction Set Computer) systems can be implemented in CISC (Complex Instruction Set Computer) systems, such as a load/store architecture that separates memory access and arithmetic operations. Additionally, the use of a larger number of registers to minimize memory access can enhance performance in CISC systems. Furthermore, CISC architectures can adopt pipelining techniques, allowing for overlapping instruction execution to improve throughput. Lastly, simplifying instruction decoding can also be integrated to streamline the execution process in CISC designs.

What is the circuit of Super computer?
Super computers are complex machines generally consisting of multiple computers or processor subsystems clustered or connected together to perform super computing tasks which need execution of many billions of instructions in a second. These are too complex for any one to be a able to draw a circuit or schematic of a super computer.
Contrast CISC and RISC technology?
