The single-thread performance of a processor improves the capability of the entire system by
reducing the critical path latency of programs. Typically, conventional superscalar …

Out-of-order superscalar processors are currently the only architecture that speeds up
irregular programs, but they suffer from poor power efficiency. To tackle this issue, we …

The renaming unit of a superscalar processor is a very expensive module. It consumes large
amounts of power and limits the front-end bandwidth. To overcome this problem, an …

Graphics processing units (GPUs) have been introduced in various fields due to their high
parallel computing performance. A key feature of GPUs is multi-threaded execution, where a …

A graphics processing unit (GPU) is a processor that achieves high throughput by exploiting
data parallelism. We found that many GPU workloads also contain instruction-level …

The single-thread performance of a processor core is essential even in the multicore era.
However, increasing the processing width of a core to improve the single-thread …

Register renaming is the key for the performance of out-of-order processors. However, the
release mechanism of the physical register may cause a waste from time dimension. The …

The time taken for processor simulation can be drastically reduced by selecting simulation
points, which are dynamic sections obtained from the simulation result of processors. The …

Superscalar microarchitectures include register renaming units where architectural registers
are renamed to physical registers. Modern renaming units are required to rename more than …

Register renaming unit is a bottleneck in the superscalar cores because it limits the number
of instructions and the number of threads that may concurrently be processed. We propose a …
