The main memory system is a critical component of modern computer systems. Dynamic Random Access Memory (DRAM) based memory designs dominate the industry due to mature device technology and low cost. These designs, however, face several challenges moving forward. These challenge…

Instruction fetch throughput is one of the most significant performance bottlenecks of a Simultaneous Multithreading Processor. Instruction fetch throughput limits the execution throughput of a Simultaneous Multithreading Processor even when the processor supports a large number…

One of the major limiters to computer systems and systems on chip (SOC) designs is accessing the main memory, which is typically two orders of magnitude slower than the processor. To bridge this gap, modern processors already devote more than half of the on-chip transistors to t…

A larger instruction window on Out-of-Order (OoO) cores facilitates better exploitation of inherent Instruction Level Parallelism (ILP). Branch miss-speculation penalty restricts scaling to larger instruction window in OoO cores. Branch instructions dependent on hard-to-predict …
