• The design space of register renaming techniques

  日期：——

  Register renaming is a technique to remove false data dependencie-write after read (WAR) and write after write (WAW)-that occur in straight line code between register operands of subsequent instructions. By eliminating related precedence requirements in the execution sequence of the instructions, renaming increases the average number of instructions that are available for parallel execution per cycle. This results in increased IPC (number of instructions executed per cycle). The identification and exploration of the design space of register-renaming lead to a comprehensive understanding of this intricate technique. As this article shows, the design space of register renaming is spanned by four main dimensions: the scope of register renaming, the layout of the rename buffers, the method of register mapping, and the rename rate. Relevant aspects of the design space give rise to eight basic alternatives for register-renaming. In addition, the kind of operand fetch policy significantly affects how the processor carries out the rename process, which duplicates the eight basic alternatives to 16 possible implementation schemes. The article indicates which basic implementation scheme is used in relevant superscalar processors. As register renaming is usually implemented in conjunction with shelving, the underlying microarchitecture is assumed to employ shelving.

  寄存器重命名是一种消除错误数据依赖性的技术--读后写（WAR）和写后写（WAW）--这种错误数据依赖性出现在后续指令的寄存器操作数之间的直线代码中。通过消除指令执行顺序中的相关优先级要求，重命名可增加每个周期可用于并行执行的指令平均数量。这就提高了 IPC（每个周期执行的指令数）。通过识别和探索寄存器重命名的设计空间，可以全面了解这一复杂技术。正如本文所述，寄存器重命名的设计空间主要包括四个方面：寄存器重命名的范围、重命名缓冲区的布局、寄存器映射方法和重命名率。设计空间的相关方面产生了八种基本的寄存器重命名方案。此外，操作数取回策略的种类也会对处理器如何执行重命名过程产生重大影响，这就将八种基本备选方案重复为 16 种可能的实现方案。文章指出了相关超标量处理器采用的基本实现方案。由于寄存器重命名通常是与搁架一起实施的，因此假定底层微体系结构采用搁架。
