processor operations

[stealth_blade]

processors perform two operations on a clock cycle
well, amd does, intel can only do one or the other but i cant remember what theyre called.

any help?

Is this what u mean?

Out-of-order execution is another important technique for keeping a superscalar processor busy. A superscalar processor can execute more than one instruction at a time. If it has to execute instructions strictly in order, however, it will often get stuck waiting for one instruction to be completed. For example, one instruction might load a data item from memory. If this data item is not found in the cache, then many processor clock cycles will go by before the data is returned from memory. An out-of-order processor allows the processor to move on to the next instruction in this circumstance, as long as that instruction doesn't use the data for which the load instruction is waiting.

predecode information and the x86 instructions are stored in the instruction cache, which will be used later by the decoders. The decoders then translate up to two x86 instructions per clock cycle into RISC instructions, called RISC86 instructions or operations. Then four RISC86 instructions are sent to the scheduler buffer, which dispatches the instructions to the different execution units (7).

And what about hyperthreading?

Hyper-Threading creates logical processors to handle multiple threads in the same time slice a single physical processor would normally only be able to handle a single operation
