There is still considerable controversy among experts about which architecture is better. Some say that RISC is cheaper and faster and therefor the architecture of the future.
Others note that by making the hardware simpler, RISC puts a greater burden on the software. Software needs to become more complex. Software developers need to write more lines for the same tasks.
Therefore they argue that RISC is not the architecture of the future, since conventional CISC chips are becoming faster and cheaper anyway.
RISC has now existed more than 10 years and hasn't been able to kick CISC out of the market. If we forget about the embedded market and mainly look at the market for PC's, workstations and servers I guess a least 75% of the processors are based on the CISC architecture. Most of them the x86 standard (Intel, AMD, etc.), but even in the mainframe territory CISC is dominant via the IBM/390 chip. Looks like CISC is here to stay …
Is RISC than really not better? The answer isn't quite that simple. RISC and CISC architectures are becoming more and more alike. Many of today's RISC chips support just as many instructions as yesterday's CISC chips. The PowerPC 601, for example, supports more instructions than the Pentium. Yet the 601 is considered a RISC chip, while the Pentium is definitely CISC. Further more today's CISC chips use many techniques formerly associated with RISC chips.
So simply said: RISC and CISC are growing to each other.
ARM7 is an architecture, not a specific model. ARM7 processor can be made by any licensee of the technology to suit their needs. As such, their clock frequencies can range anywhere from 1 Mhz to 2.5 GHz.

risc
Its exactly what is says on the tin. A 32-bit processor that uses the ARM9 architecture.
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.
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.
RISC in DBMS stands for Reduced Instruction Set Computer. It refers to a type of processor architecture that focuses on the simplicity of instructions to improve performance. In database management systems, RISC processors can optimize query processing and data manipulation tasks efficiently.
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.
