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.
"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".
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.
Microoperations are fundamental operations that can be performed by a digital computer's control unit at a very basic level, usually involving simple data manipulation or transfer tasks. These operations form the building blocks for more complex instructions and tasks executed by a computer's central processing unit (CPU). They are essential for controlling the flow of data and instructions within a computer's architecture.
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.
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.

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.
It provides more instructions than RISC (Reduced Instruction Set Computer).
