CPU 通常包括两个独立的内存空间:寄存器堆和内存。现代 GPU 在逻辑上将内存进一步细分为局部(local) 和全局(global) 内存空间。局部内存 (local memory) 空间是每个线程专用的,通常用于寄存器溢出,而全局内存 (global memory) 用于在多个线程之间共享的数据结构。此外,现代 GPU 通常实现程序员管理的暂存器内存 (scratc...
另一方面,单线程顺序 CPU 的记分板非常简单:记分板中的每个寄存器都用 1 bit 表示,只要发射将写入该寄存器的指令,就会置位该 bit。任何想要读取或写入在记分板上置位了相应 bit 的寄存器的指令都会停止 (stall),直到该 bit 被写入寄存器的指令清除。这可以防止先写后读 (RAW) 和先写后写 (WAW) 冒险。当与...
Recent announcements such as a server product with an FPGA integrated with a CPU make the possibilities even more intriguing.Rajwar, RaviDixon, MartinSinghal, RonakR. Rajwar, M. Dixon, and R. Singhal, "Specialized evolution of the general purpose cpu." in CIDR, 2015....
在编程模式中，GPGPU的计算流程由CPU启动，分配内存并传输数据，然后发射计算内核到GPU执行。计算内核包含数千个线程，执行相同的程序。执行模型涉及GPU指令集架构（ISA），NVIDIA和AMD的ISA分别具有不同的特性。SIMT（Single Instruction Multiple Thread）核心是GPGPU架构的关键部分，它涉及指令和寄存器数据流的...

I demonstrate the effectiveness of the proposed approaches by performing cycle-accurate simulations of a chip multiprocessor consisting of two four-way superscalar cores running the single-threaded SPEC CPU2000 benchmark suite. The proposed mechanisms provide significant performance improvements over a ...
