| | Processor register - Wikipedia, the free encyclopedia |
 | | In computer architecture, a processor register is a small amount of very fast computer memory used to speed the execution of computer programs by providing quick access to commonly used values—typically, the values being in the midst of a calculation at a given point in time. | | | Registers are now usually implemented as a register file, but they have also been implemented using individual flip-flops, high speed core memory, thin film memory, and other ways in various machines. | | | The term is often used to refer only to the group of registers that can be directly indexed for input or output of an instruction, as defined by the instruction set. |

| | It's mainly because the processor has to go out to the memory bus to read or write the memory location and wait until the operation completes before moving on to the next instruction. | | | The register stack is used for input parameters, local variables, and return values of functions (see Figure 2). | | | Any processor instruction that uses memory takes more time to execute than the same instruction that uses a processor register. |

| | When the processor notices that Wait is no longer asserted, it latches data into the MBR on a read or tri-states the data connection to memory on a write. | | | A processor control unit is considerably more complex than the kinds of finite state machines you have seen so far. | | | A bidirectional path for load/store data exists between the processor data-path and the MBR, while the pathway for instructions between the MBR and IR is unidirectional. |

| | The Pentium III processor is based on the same well-known foundation as the Pentium II processor, and as such, many of the software design principles and optimization techniques still apply. | | | To make the most of your game on Pentium III processor based systems, you have to know how to optimize you game for the new processor, and that in turn requires that you understand the processor's architecture. | | | With this in mind, the best optimization tool with which to arm yourself is a basic understanding of how the processor executes code (see Sidebar 1, "Understanding the Pentium II Processor"). |

| | r_harvey - 8086 Processor Registers |
| | Most processor memory instructions assume that we are manipulating data in the default data segment. | | | One way to read the IP register is with a near call instruction, which places the value of the instruction pointer on the stack. | | | Copying between registers is straightforward; for semantic clarity (of which that phrase is not an example), we specify the source and destinations directly. |

| | Register windows are also used to save the processor contexts when traps, or interrupts occur. | | | On processors that use delayed branches but cannot annul the delay instruction, the compiler must try to fill the delay slot whether or not the branch is taken. | | | The CALL instruction automatically saves its own address in 07 (output register 7) which becomes input register 7 if the CWP is decremented. |

| | Power of two |
| | Nearly all processor registers have sizes that are powers of two (32 being currently used in most personal computers). | | | Because modern memory cells and registers often hold a number of bits which is a power of two, the most frequent powers of two to appear are those whose exponent is also a power of two. | | | Powers of two occur in a range of other places as well. |
