## About the Role

* Master's or PhD in Computer Science, Engineering, Physics, or related field.
 * Strong knowledge of superscalar processor design, speculative execution, and out-of-order execution.
 * Experience with cycle-accurate microarchitecture simulation and performance modelling.
 * Strong programming skills in C, C++, Python, and Arm64 or RISC-V assembly.

## Description

We are partnered with a globally renowned research center in the UK looking to expand their team with a CPU Research Engineer to research and develop novel microarchitectural techniques targeting IPC and energy efficiency improvements for next-generation mobile CPUs.

This is a 12-month PAYE engagement based onsite in Cambridge, UK., * Research and develop novel out-of-order execution techniques to improve IPC and energy efficiency of mobile CPUs.

 * Analyse and optimise front-end pipeline stages including branch prediction, fetch, and decode.
 * Investigate bottlenecks in the OOO backend - issue queues, register renaming, reorder buffer, and execution units.
 * Develop and maintain cycle-accurate microarchitectural simulation models (e.g. gem5) to evaluate OOO design trade-offs.
 * Conduct workload characterisation and microarchitectural profiling using hardware performance counters and simulation.
 * Evaluate and integrate state-of-the-art academic research into practical CPU design proposals., Keywords: CPU Research Engineer / Microarchitecture / Out-of-Order Execution / Branch Prediction / Superscalar / gem5 / Cycle-Accurate Simulation / Mobile CPU / IPC / Energy Efficiency / C / C++ / Python / Arm64 / RISC-V / LLVM / GCC / Compiler / Performance Modelling / Cambridge / UK
