The advantages are that a simpler instruction set found in a RISC processor are easier for compilers to write programs in, as well as the simple design of the processor that is allowed to result from this simple instruction set. In the past, CISC processors were used when people had to program in the assembly language of the processor itself. These processors had many different instructions that could perform complicated operations with one instruction, making the assembly programmers life easier. Eventually, we wrote programs called compilers which converted high level languages, such as C, into these assembly instructions. As C is much easier to program in than assembly language, this made our lives even easier. Unfortunately, it was found that it was difficult to program a compiler in such a way that it could realise when these complicated instructions offered by the CISC processor would be useful. This, in addition to the fact that some complicated instructions were actually slower than a series of simple instructions that performed the same task, meant that it was easier to write compilers that only used the simple instructions. By cutting out the complicated instructions, simpler processor designs could be used, and this is, in essence, what a RISC processor is. Of course, the most popular desktop architecture today, x86, is a CISC processor, but this was a case of people unwilling to change to a different instruction set. Ultimately, modern processors which use the x86 architecture actually convert the CISC instructions of the architecture into a simpler RISC-like series of instructions, before being executed on the processor. So, to sum up: + simpler processor design + simpler instruction set + easier for compilers to write programs for

Programming a RISC processor is harder at the assembly language level, but they weren't designed to be programmed that way. RISC instruction sets are architected to be most efficiently programmed using optimizing compilers for High Level Languages.
CISC processors when given typical compiler generated code, rarely used more than 10% of the instructions and therefore waste almost all of the implemented hardware functions.

What is arm9 risc 32-bit processor?
Its exactly what is says on the tin. A 32-bit processor that uses the ARM9 architecture.
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.
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.
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.
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.
Which machine tend to make use of internal resources of the processor and a rich set of registers and a pipelined organization?
RISC
