The Functions of the instruction set is to instruct All CPU's with a set of instructions:
Tells the CPU where to find data
When to read the data
What to do with the data.
Hope that helps

They tell the CPU where to find the data, when to read it, and what to do with it.
Planned x86 processors will have the SSE4 instruction set.
The entire set of instuctions that a CPU can execute is known as the CPU INSTUCTION SET.
It is a system of coded numbers that when read by the CPU control unit are interpreted as commands for the various operations it can perform. Each different type of CPU has a differently coded instruction set.
CISC (complex instruction set computing)
The set of instructions, on the CPU chip, that the computer can perform directly.
The set of instructions, on the CPU chip, that the computer can perform directly.
The CPU's instruction set is not stored anywhere. Rather, it is an integral part of the silicon that the CPU is made out of. The "instruction set" is actually a metaphor used to describe the different effects of charges at different points in the CPU. Just because I call a certain operation "add" doesn't mean anything to the CPU. Charges are applied and due to the way they are applied, different transistors open and close, providing different effects.
Yes, Instruction Set is the list of OPCODES that CPU (Processor) understands & performs on those instructions (i.e. enables devices to communicate, process received instructions & directing towards the right output devices).
3DNOW is the technology that AMD processors use for multimedia instruction set.
machine code instruction set or assembly language
A CPU will have an "instruction set" which consists of primitive instructions i.e a command like MOVE:1002,1003 could be an example of an instruction to move the contents in memory location 1002 to the memory location of 1003. Some CPU's operate as a RISC (Reduced Instruction Set Computer) and others operate as a CISC(Complex Instruction Set Computer). Which basically means some have more "primitive instructions" than others but the more complex an instruction is - The more work will be needed to execute it. Alan Turing proved only 6 of these primitive commands are needed to compute anything that is "computable" by machines. Nowadays, programmers will write code in an "high level" language which contains more of these "primitive commands" but then the code will be compiled into a set of instructions that the CPU can actually execute (i.e to the instruction set of the targeted CPU). If we were to try to write any sufficiently complex program using only the instruction sets of CPU's, it would become very complicated for humans to understand and would take a ridiculously long time.
