RISC architectures generally have fewer instructions that operate directly on memory locations than CISC architectures. So, where a CISC machine will have instructions that operate directly on memory, in RISC this would be implemented as: Load from memory into register, do operation on register, store register back into memory. So a lot of the processing revolves around the Load-Store loop.

What are two roman contributions to architectures?
Two Roman contributions to architecture are the dome and the Tuscan order of column.
What are the different types of CPU designs?
Too many to even begin to list here, forget describing the architectures.
What invention made it possible for computers to process information very quickly and made computers more affordable?
PowerPC (short form of Performance Optimization With Enhanced RISC-Performance Computing,sometimes abbreviated as PPC) is a RISC computer architecture created by the 1991 APPLE-IBM-MOTOROLA alliance known as AIM. ...Originally invented for personal computers.PowerPC cpus since became very popular as embedded and high performance processors and thus made computers more affordable.. hope i helped a bit :)
What form of art is special to Egypt?
Egypt is known for its colossal pyramids, temples and tombs. The most well known Egyptian architectures are the Pyramid of Djoser, the Sphinx and the temple of Abu Simbel.
What are the advantages of RISC architecture over CISC?
CISC RISC Emphasis on hardware Emphasis on software Includes multi-clockcomplex instructions Single-clock,reduced instruction only Memory-to-memory:"LOAD" and "STORE"incorporated in instructions Register to register:"LOAD" and "STORE"are independent instructions Small code sizes,high cycles per second Low cycles per second,large code sizes Transistors used for storingcomplex instructions Spends more transistorson memory registers RISC-Means Reduced Instruction Set Computer.aRiscsystem has reduced number of instructions and moreimportantly it is load store architecture werepipelining can be implemented easily.Eg.ATMEL AVRCISC-Means Complex instruction set architecure.A CISCsystem has complex instructions such as directaddition between data in two memory locations.Eg.8085Simplicity of the instruction set means that they get processed faster (less branching). You get performance improvements if the gain in speed is not offset by the necessary increase in instructions.
Does Linux work on RISC processors?
Sure, Linux is ported to a number of different RISC architectures, including ARM and PPC.
What are the advantages and disadvantages of risc?
RISC (Reduced Instruction Set Computer) architectures offer advantages such as simplified instruction sets, which lead to faster execution and easier pipelining, resulting in higher performance and efficiency. Additionally, RISC designs can be more power-efficient, making them ideal for embedded systems. However, disadvantages include a potentially higher number of instructions to perform complex tasks, which can lead to increased memory usage. Furthermore, RISC architectures may require more sophisticated compiler designs to optimize code effectively.
Which CPU architectures uses a small set of instruction that are designed to be executed rapidly?
RISC Stop cheating on the Cisco test NEVER!!!!! cheating is the easy way who whatn to do it the hard way
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.
What are the different types of instructions in a RISC machine?
Well, different RISC architectures can (and do) have different instruction sets, but the basics I can think of (thinking back to my computer org classes, long ago) that any would have would be add, subtract, branch, store and retrieve. Basically, anything else can be built from those.
WHAT part of the processor is responsible for directing actions performed by the processor?
When an instruction reaches a microprocessor it arrives at an internal block known as a "microcode sequencer" which is present in CISC architectures. This microcode sequencer then steps through a series of locations in the microcode ROM and issues control signals to the various registers, multiplexers, ALU, etc in the microprocessor. RISC architectures lack this microcode sequencer, but have a similar construct known as a microcode translator or interpreter. Because RISC machines must complete execution in a single clock cycle, there aren't any "steps" to cycle through. Remember that RISC instructions are inherently more simple than CISC instructions.
What platforms does HP-UX run on?
HP-UX runs on the PA-RISC and IA-64 (Itanium) architectures. Earlier versions also ran on certain m68k equipment.There is currently no version for x86 or x86-64.
