| 摘 要： | 应用的需求促使如今的处理器必须尽可能高地利用程序中所存在的指令级并行度,然而,高指令级并行的硬件和指令调度技术会给寄存器资源带来极大的压力.要在单一寄存器堆的情况下,既维持高的指令级并行度,又保持高的运行时钟频率是一件非常困难的事情,这是因为,当指令级并行度足够高时,在单一寄存器堆情况下,寄存器堆访问端口数目的限制会使...

| Abstract: | Applications,especially the multimedia processing applications,have put an increasingly performance requirement on today's computer architectures.Many today's computer architectures typically are taking increasing advantage of the instruction-level parallelism(ILP) available in programs.Unfortunately,large amounts of ILP hardware and aggressive instruction scheduling techniques put large demands on a machine's register resources.With large amounts of ILP,it becomes difficult to maintain a single monolithic ... |
