Sr. Principal SOC Fabric Architect
Confirmed live in the last 24 hours
Austin, TX, USA
Experience Level
  • Strong grasp of NoC topologies, routing algorithms, queuing, traffic scheduling, and QoS requirements
  • Expertise in cache coherency protocols (AMBA CHI/AXI protocol), DDR/LPDDR/GDDR memory technology, and IO technology (PCIe/CCIX/CXL)
  • Proficient in C/C++ programming. Experience in the development of highly efficient C/C++ CPU models
  • Collaborate with the software team and platform architecture team to understand fabric bandwidth and latency requirements and real-time constraints for AI accelerator, CPU, security, and networking traffic. Devise QoS and ordering rules among the CPU, accelerator, and IO coherent/non-coherent traffics
  • Identify representative traffic patterns for the software applications. Perform data-driven analysis to evaluate fabric topology, QoS, memory architecture , and u-architecture solutions to improve performance, power efficiency, or reduce hardware
  • Create directory-base cache coherency specification to satisfy performance requirements of coherent multiple-cluster CPU system and accelerator. Tradeoff protocol complexity and performance requirements
  • Design cache hierarchy to create best performance
  • Set SoC architecture direction based on the data analysis and work with a cross-functional team to achieve the best hardware/software solutions to meet PPA goals
  • Develop a SoC cycle-accurate performance model includes memory sub-systems, directory-base coherent cache controllers, fabric interconnects, and fabric switches that describes the microarchitecture, use it for evaluation of new features
  • Collaborate with RTL and Physical design engineers to make power, performance, and area trade-offs
  • Drive analysis and correlation of performance feature both pre and post-silicon
Desired Qualifications
  • Prior experience or strong understanding of traffic patterns for ML/AI algorithms in a heterogeneous computation system is a plus
  • Prior experience on formal verification of cache coherency protocol is a plus
