Role Overview

As a CPU Integration Engineer at DEEPX, you will play a pivotal role in the development of our next-generation AI Inference Solutions. You will be responsible for integrating high-performance CPU subsystems into our NPU-centric SoCs, ensuring seamless communication between the processing cores, memory hierarchy, and our proprietary AI accelerators. This role sits at the intersection of architecture design and physical implementation, requiring a deep understanding of bus protocols and system-level performance.

Responsibilities

Subsystem Integration: Integrate ARM or RISC-V based CPU IP into AI SoC platforms, focusing on top-level connectivity and hierarchy.

Bus & Interconnect Design: Design and configure high-speed on-chip interconnects (NoC/NIC) using protocols such as AMBA (AXI, ACE, CHI) to ensure low-latency data paths.

Memory Hierarchy Management: Define and optimize the integration of L2/L3 caches, Snoop Control Units (SCU), and memory controllers.

Architecture Validation: Perform RTL-level integration checks, linting, and CDC (Clock Domain Crossing) analysis to ensure design integrity.

Performance Tuning: Collaborate with the Architecture team to analyze and resolve system bottlenecks related to CPU-to-NPU communication.

Cross-functional Collaboration: Work closely with Front-end/Back-end teams and Software/Firmware teams to define boot sequences and power management schemes.

Qualifications

□ Experience in Cortex-A series and multi-cluster integration required.

Education: Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related technical field.

Experience: 5+ years of experience in SoC integration or RTL design.

Technical Skills: * Proficiency in Hardware Description Languages (Verilog, SystemVerilog).

  • Strong understanding of AMBA protocols (AXI4, ACE, CHI).
  • Experience with CPU IPs (ARM Cortex-A/R/M series or RISC-V).
  • Familiarity with SoC design flows and EDA tools (e.g., Synopsys Platform Architect, Cadence Genus).

Preferred Qualifications

□ Experience of FPGA Implementation

NoC Expertise: Hands-on experience with Network-on-Chip (NoC) IP (e.g., Arteris, ARM CoreLink).

Low Power Design: Knowledge of UPF/CPF based power intent and multi-voltage domain integration.

Security Integration: Experience integrating hardware security modules (TrustZone, Root of Trust).

Advanced Nodes: Experience in advanced process nodes (5nm, 4nm, or below).

Problem Solving: A proactive mindset with the ability to navigate the complexities of cutting-edge AI hardware.
