Multicore processors have become ubiquitous in today’s systems, but exploiting the parallelism they offer remains difficult, especially for legacy application and applications ...
In superscalar architectures, out-of-order issue mechanisms increase performance by dynamically rescheduling instructions that cannot be statically reordered by the compiler. Whil...
Ensuring back-to-back execution of dependent instructions in a conventional out-of-order processor requires scheduling logic that wakes up and selects instructions at the same rat...
Although SIMD (Single Instruction stream Multiple Data stream) parallel computers have existed for decades, it is only in the past few years that a new version of SIMD has evolved...
Data-parallel architectures like SIMD (Single Instruction Multiple Data) or SIMT (Single Instruction Multiple Thread) have been adopted in many recent CPU and GPU architectures. Al...
