Performance Verification of the AmpereOne CPU Core
Doa'a Al-Otoom, Nicholas Kelly, Aaron Lindsay +16
As process technology scaling slows, microarchitectural innovation has become the primary driver of performance gains, making pre-silicon Performance Verification (PV) more critica…
SPEC CPU: The Next Generation
Mahesh Madhav, Allen Lee, Andres Mejia +33
The march toward developing relevant and robust CPU benchmarks continues with the introduction of SPEC CPU 2026, the next generation suite for measuring processor performance. This…
Optimized Memory Tagging on AmpereOne Processors
Shivnandan Kaushik, Mahesh Madhav, Nagi Aboulenein +14
Memory-safety escapes continue to form the launching pad for a wide range of security attacks, especially for the substantial base of deployed software that is coded in pointer-bas…
ARM MTE Performance in Practice (Extended Version)
Taehyun Noh, Yingchen Wang, Tal Garfinkel +4
We present the first comprehensive analysis of ARM MTE hardware performance on four different microarchitectures: ARM Big (A7x), Little (A5x), and Performance (Cortex-X) cores on t…
Memory Access Vectors: Improving Sampling Fidelity for CPU Performance Simulations
Sriyash Caculo, Mahesh Madhav, Jeff Baxter
Accurate performance projection of large-scale benchmarks is essential for CPU architects to evaluate and optimize future processor designs. SimPoint sampling, which uses Basic Blo…
