Workplace: Onsite
Employment Type: Full time
Job Function: Solutions Engineering & Sales Engineering

Key Responsibilities

  • •Improve the benchmarks and real-use-case performance (IPC, power/area efficiency) of a state of the art OoO CPU core, covering core pipelines, branch prediction, prefetching, and cache/TLB hierarchy.
  • •Work with the performance simulation team to model the microarchitecture of the SOTA core.
  • •Correlate simulation results against silicon measurement data, and perform root cause analysis and debugging to identify discrepancies, ensuring model accuracy and reliability.
  • •Explore new features and ISA extensions (e.g., vector extensions, memory safety features, security enhancements) to drive performance improvements and reliability.
  • •Identify and resolve performance bottlenecks through modeling and prototyping.
