What is a CISC processor?

Anonymous

∙ 12y ago

Updated: 12/10/2022

"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 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.

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 has less number of instruction risc or cisc?

RISC stands for Reduced Instruction Set Computer. The design strategy of a RISC processor includes limiting the number of instructions. This does not mean that ALL RISC processors have less instructions than ALL CISC processors, but in general, they do.

Can you give me three examples of RISCreduce instruction set computer?

good example for RISC processors is DSP (Digital signal processing) processors. simillarly for cisc processors is microprocessor.we can understand the difference between these two by a simple example. here it is, Convolution in terms of DSP is nothing but continuous multiplication. cisc processor performs multiplication by continious addition.but risc processor perform continious multiplication in a single pipeline architecture.
