  2. Register renaming - Wikipedia

    en.wikipedia.org/wiki/Register_renaming

    The rename file must have a read port for every input of every instruction renamed every cycle, and a write port for every output of every instruction renamed every cycle. Because the size of a register file generally grows as the square of the number of ports, the rename file is usually physically large and consumes significant power.

  3. Tomasulo's algorithm - Wikipedia

    en.wikipedia.org/wiki/Tomasulo's_algorithm

    Tomasulo's algorithm uses register renaming to correctly perform out-of-order execution. All general-purpose and reservation station registers hold either a real value or a placeholder value. If a real value is unavailable to a destination register during the issue stage, a placeholder value is initially used.

  5. Rename (computing) - Wikipedia

    en.wikipedia.org/wiki/Rename_(computing)

    The C standard library provides a function called rename which does this action. [1] In POSIX, which is extended from the C standard, the rename function will fail if the old and new names are on different mounted file systems. [2] In SQL, renames are performed by using the CHANGE specification in ALTER TABLE statements.

  6. Loop unrolling - Wikipedia

    en.wikipedia.org/wiki/Loop_unrolling

    On hardware where software pipelining is necessary to improve performance alongside loop unrolling (i.e. hardware which lacks register renaming or implements in-order superscalar execution), additional registers may need to be used to store temporary variables from multiple iterations that could otherwise reuse the same register. [7]

    In the following examples, computed values are in bold, while Register numbers are not. For example, to write the value 3 to register 1, (which already contains a 6), and then add 7 to register 1 and store the result in register 2, i.e.: i0: R1 = 6 i1: R1 = 3 i2: R2 = R1 + 7 = 10. Following execution, register 2 should contain the value 10.

  8. Register file - Wikipedia

    en.wikipedia.org/wiki/Register_file

    This same technique is used in the R10000 register renaming mapping file, which stores a 6-bit virtual register number for each of the physical registers. In the renaming file, the renaming state is checkpointed whenever a branch is taken, so that when a branch is detected to be mispredicted, the old renaming state can be recovered in a single ...

  9. Register window - Wikipedia

    en.wikipedia.org/wiki/Register_window

    Example of a 4-window register window system. In computer engineering, register windows are a feature which dedicates registers to a subroutine by dynamically aliasing a subset of internal registers to fixed, programmer-visible registers. Register windows are implemented to improve the performance of a processor by reducing the number of stack ...
