If you’ve been reading Ars for any length of time, then you know that there are two terms that always come up in any of my articles: pipelining and superscalar execution.

We will admit it: mostly when we see a homebrew CPU design on an FPGA, it is a simple design that wouldn’t raise any eyebrows in the 1970s or 1980s. Not so with [Henry Wong’s] design, t… ...

Dr. Rosa Badia from BSC/CNS presented this Invited Talk at SC15. "StarSs (Star superscalar) is a task-based family of programming models that is based on the idea of writing sequential code which is ...

It is often assumed that a superscalar architecture will require complex logic for pipeline control, and therefore will have high overhead in terms of power consumption. This assumption stems from the ...

At Interop 2009 in Las Vegas this week, RMI Corp unleashed its Superscalar XLP processor, the highest performing in the industry with unmatched system and performance scalability, the company said.

The superscalar microarchitecture of the V5 core increases the number of instructions that can be executed simultaneously, thereby increasing the performance of the core. With dual execution pipelines ...

A new technical paper titled “Ramping Up Open-Source RISC-V Cores: Assessing the Energy Efficiency of Superscalar, Out-of-Order Execution” was published by researchers at ETH Zurich, Università di ...

In a superscalar design, it would require an enormous number of wires to connect each register directly to each ALU. This problem gets worse as the number of registers and ALUs increases.
